Here are a couple of ways that you can create what you need.
[A] Expanding the view so you can work on the second-time-through bars.
1) Go to BIAB's standard view. (CTRL+T is the toggle to go between full-screen and standard views).
2) Click on "Fakesheet" (#1 on the image below).
3) Remove the check against "Display chordsheet in fakesheet mode". (#2).
4) Click on the "Bass" track to give it the focus. The message you received about "no realtracks on this track" is because the focus was on a different track (probably the Melody track).

When you uncheck this, you will see all your repeat chords. BIAB lays out the chordsheet in the same linear fashion that it plays it. The repeated sections will be grayed out. Like before, you can work on these grayed out bars using Multiriff (F8) to partially regenerate and change the bass to how you want it. When you have finished, activate option #2 again and the chordsheet will return to a fakesheet mode of display.
[B] Using Audio Edit
