Is there a way to bake the AOVS i create?

[lucialeila]

I'm doing a haircap for a model using xgen. So far I've baked with marmoset, but the thing is that 

1. I can't bake flow/direction map.

2. Every map looks different than what I've done for the haircards since I've done those using Arnold.

I have all the AOVs (The ones I've used for the haircards). Is there anyway to bake all the aovs I've created using Maya / Arnold? It's urgent
