Depth Maps for color correction

Hey everyone,

I'd like to know if Resolve will ever have a depth map calcutor? It could be so nice to mask area with a z depth map!

I know there's yuvsoft on the market but only for AE and Nuke!

I have some shots that I would like to mask the background but I'll forget that instead of doing hours and hours of rotoscoping.

Do you know any workflow in resolve to do a depth pass?

Thanks

SGO Mistika... is really good at that...
