<< I have premade wave stem files that I am using to import into BIAB. And then I'm using BIAB to enter the chords and lyrics and create a lyric video. I import all 9 files into the utility tracks ... I can't line them up with the bars in BIAB because the only way to do this is if all the tracks are on one file. >>

BIAB has the option to align individual audio files imported into the Audio Track and all 16 Utility Tracks.

In your example, you should import the stems into Utility Tracks 1-9 and from the Audio Editor;
Place the curser at Bar one of the audio file
Right Click anywhere in the Wave Form Window and select "make this point as Bar 1 of the song .." option

Repeat for each of the other 8 imported audio files and this aligns each track's bar 1 to Bar 1 of the BIAB Chord Chart
