Good question and I do not have a clue. MatN would probably know immediately. But I will see if I can figure this out later today. I do see around page 457 in the pdf version of the manual, the following statement; however I probably just jammed that in without doing a thorough investigation.

You can add your own images to the Shape Wipe transition and there are some
free ones available to download at http://assistcg.com - click on the Transi-
tions option under the Video pulldown on that site. AppImage does not provide
this capability unless you use the workaround as described in the Appendix FAQ,
Known Problems and Workarounds.

I received a request to put a button that would serve to put new
transitions directly into the appimage. In your opinion is it possible
or do you have to go through manual unpacking and subsequent
recreation of the appimage?
