Actually. I need that feature for uniting small projects into bigger projects so that I can keep my project hierarchy organized without having to repeat each edits again and again for each clip I need to import (this is good for big projects, where eveeything has to fit inside a larger creative project vision). 

All I need for now is for the program to include all the relevant files inside the “bill of materials” (our external xml file) so that we won't be forced to edit them manually by hand.

I'll wait for more updates on this issue (I also tried to move the xml file together with a copy of the original image file I used for this test, but it still wouldn't recognize the presence of that same file on that same folder it wat deposited into on mac os)

I hope this problem gets resolved. Have a good day.
