I use the image container on a fairly regular basis, but not often enough to remember each time the subtleties in the Output Template syntax.
I would see it as a huge advantage to give a preview of what will be the name of the file or files produced after launching the process, based on the syntax we are entering, but BEFORE effectively starting the process.
This would remove so many uncertainties as to the correct syntax to use and would reduce the number of (long) process abortions due to a bad syntax in the output template, which often result with unwanted "&" or ";" or other unwanted strings in the resulting filenames...
It would be a huge time saver!
Thanks to consider!
