Is "Save as Band in a Box Song *.g.*" supposed to work?

It shows as exporting the tracks to Utility Tracks, but when opening the file in BIAB 2022 Build 912, RealBand 2022 (2) (Earlier builds same problem)... nothing shows up on the utility tracks.

I've attempted this multiple times, in multiple versions of RealBand and BIAB, over many months, with same results. It would be a nice feature, if it worked.

Thanks
