Hi Chris -
Another possibility is to highlight the process icons you wish to transfer and then right-click on the workspace, select
Process Icons/Save Process Icons.... Save the icons with the name z.xpsm.
Open the second project, right-click on the workspace, select Process Icons/Load Process Icons.... Double click on the z.xpsm file and, voila, there are the process icons with all the same settings.
Hope this helps.
Steve
