There in no F5 change loop at bar #
There is A part B part Loop choice but no Ending

So if you could drag n drop Loops out of the Loop Picker into the Audio Editor Tracks or to make it easy to program just have a button to insert Loop @ bar # for x bars and they would automatically adjust tempo and pitch with a local dB +- adjust, you would also be able to Play/Preview from bar x in situ to hear if it fits in with the other BB Tracks.
This will save the Loop data when track is frozen.
