I'd appreciate help setting up a 12-bar blues backing track just the way I want it (in BB 2020 Win)...

Here's what I'm trying to do:

choruses 1 - 4: just the selected style track
choruses 5 & 6: adding soloist tracks
choruses 7 - 9: trading 2's with a soloist track
chorus 10: just the selected style track

I think that by selecting "mute melody in middle", I can inactivate trading 2's in choruses 1 and 10, and I think that adding soloist tracks for choruses 5 and 6 will (probably?) inactivate trading 2's in those choruses, but how can I kill trading 2's in choruses 2 through 4?

Thank you!
