You can try this with Reaper if you just work in the main Biab program only and tired of dragging files over all the time.
This is just 1 Reaper script that works on any version of Biab frozen SGU/MGU, no modifications needed.
Import-frozen-SGU-MGU-realtracks-drums.zip

Just simply open a frozen SGU/MGU to instantly import the tracks into Reaper.
If you don't have the peak files already it will have to build them but once you have the reapeaks files it will be instant.
You can use Script: Create reapeaks in folder.lua

This will import new sections: Import single frozen track or section SGU MGU to selected track.lua (included with script above).
