Possible to save picture frames URLs saved by Sign Artist plugin?

The SignArtist plugin allows one to paste a URL image into picture frames/signs. I'm wondering if it's possible to have these backed up with Copy/Paste, so that next time a base is pasted, it includes the URL links to images for each respective sign?

... this works without any problem !

I noticed that if the same base is pasted multiple times, most signs will become blank after the next restart if not immediately

If the net id persists on restart. Then you could have a save list to handle that. I'll have to test.
