Thanks for the trick about naming file with Tracks.
I added it in the script, in a more flexible way (destination regions is not hard coded, and there is checking to prevent error).
The trick is to use a regions called '=RENDER', use source: regions in render settings, and set Master track for all tracks.
Let me know if it works as expected.
EDIT: Hmmmm I wonder if this works in a efficient way, especially export settings. I may have missed something. I need to make more test. let me know if it works for you.
