Rehearsal letters through multiple flows

Hello. I am trying to have separate flows form a contiguous rehearsal letter sequence (i.e., flow 2 begins with rehearsal letter B). Any way to do this?
Thanks!

you could start the second flow with a +1 offset index (select the rehearsal mark and look in properties). All subsequent mark will be offset

… as explained here. Good luck!

This works, though an option to continue sequencing from the last flow would be even better.
