Effects on individual tracks in Poly mode?

I love the poly mode (Hermod+) for having the voices being able to play the same pattern (so not having to keep copying and pasting patterns between voices) - but would it be possible to be able to put various effects on the different tracks within a poly setup? I could go the long way and do this by having 4 separate mono tracks, of course, but that would mean a whole lot of copying and pasting patterns.

It would be so neat to transpose the various tracks up and down independent of one another, perhaps put an arp on one of them etc.

Is that possible somehow, or would it be hard to implement?

Also: where do I find the poly allocator? I’ve gone through all the menus I can find, but haven’t found it.
