Yes it keeps track of everything. It essentially tells you the name of the file that you're using. I have a signature 'stamp' that I made in Photoshop Elements. I added it to a page, and then the supply list included it as a stamp with the name I had given it.
So as long as your non-SU! has a file name/directory name that reflects its origin, you're good to go.
On my Laura page, it listed each of the alphabet stamps separately ... with its colour (name and code).
