Free Warp edit for multiple tracks in group or folder

I also want to add my +1

Is there a workaround? I have a recording of my friend singing + playing the guitar, on 2 mics. He always plays outside the grid, with extra beats + half beats, just as starting point I want to have it at least align with beats.
After finding the bpm, for arranging the track I want to not warp the grid but have that constant and warp the 2 audio tracks so they align, before I take out the extra beats. Not sure how to do that with the current features in Cubase Pro 9.5
