Associate tracks

Hello

Me again, I was wondering if there is any way for me to separate a note sequence with automation for the FX ?

I had my acid line on track 16

I want to do a long automation for a song but better seperate, and I can do it on track 12 being empty for CC … but not for the internal ENV of track 16

Or I missed something ?

I think it’s really missing once again communication options between tracks
