Hello Zie,
Welcome to PixInsight Forum.
Definitely process icons are what you're looking for in PixInsight. These are the main steps:
1. Create iconsOnce you have a set of SGBNR parameters that you want to save, create a process icon from the SGBNR window. This is very easy: click on the small button labeled "<" at the bottom left corner of the window (which we call "Process Drag Object"), and drag it to the main window's background. This will create a new icon with the set of SGBNR parameters. Here is a direct link to the corresponding documentation section:
http://pleiades-astrophoto.com/pixinsight/help/11_process_icons/creating_process_icons/creating_process_icons.html#02Note that you can repeat this as many times as you want. This means that you can create hundreds of icons, each one with a different set of parameters.
2. Rename icons (optional)If you create many icons, perhaps you might want to give each of them a meaningful name (instead of Process01, Process02, etc.). Right-click on an icon and select "Set Icon Identifier":
http://pleiades-astrophoto.com/pixinsight/help/11_process_icons/managing_process_icons/managing_process_icons.html#05Giving meaningful identifiers to icons is good practice. It will help you when you reuse the icons after some time.
3. Open iconsTo open an icon, loading its parameters on the corresponding processing window, just double-click it. You can also drag it to the appropriate window if it is open.
4. Save icons to disk filesProcess icons can be saved to special disk files that we call "Process Icon Set Modules". These files carry the ".pi-psm" file extension. To save all the currently defined icons, select "Process > Process Icons > Save Process Icons..." from the main menu. Alternatively, you can right-click on any free area of the main window's background.
5. Load icons from disk filesUse "Process > Process Icons > Load Process Icons...". You also have an equivalent option by right-clicking on the main window's background, as before.
6. Merge icons from a file with existing iconsOK, you have some good icons, and you want to (a) merge them with other ones that you have in an existing file, to keep all of them into a single file, or (b) you need to work with additional icons from a file, but you don't want to throw away the icons that you have currently defined.
To merge the contents of a .pi-psm file with the current icons, just press the Shift key while you select "Process > Process Icons > Load Process Icons...". The file's contents will be loaded but existing icons will not be deleted. You can then save the resulting set of icons to the same file, or to a new one.
***********
Note that the above works with SGBNR and with any other process in PixInsight, in just the same way.
Note also that you can create icons of many different classes (processes) and save them to a unique file. There is no specific limit in the number or types of icons saved to .pi-psm files.
Process icons and process containers in PixInsight have been designed to maximize flexibility and versatility. Expect significant improvements in incoming versions, especially with respect to user interface resources dedicated to handle and organize them.
Hope this helps. Please let me know.
