Mono or stereo out choice for vsti's

I’d like to see a choice of mono and or stereo outs for vsti’s.
Especially in the case or GrooveAgent or any multitimbral vsti’s.
Also is there a way to use dissolve track on a Groove Agent midi pattern in the main arrange window and have each sound routed to the outs assigned in GrooveAgent without creating additional instances of GrooveAgent?
