Is there a feature in EOF to edit the HARM1 HARM2 HARM3 notes?

My workflow is to paste PART_VOCALS into HARM1. Then using the 2nd piano roll lineup the call and answer between HARM1 & HARM2 and again between HARM1 & HARM3

 

Thanks for all your work in EOF

There's no harmonies support in EOF.  It's been on the to-do list for a while, but so have a great number of things.  I'll basically never run out of features to work on.
