Choose download client based on indexer

OS: Debian 10

Description of issue:

I’m trying to set up sonarr. I have several indexers configured tornzab / jacket
Some are private sites and some are public.
I also have 2 download clients configured one for public and one for private. I think it’s a fairly common setup. But I can’t find any way to tell sonarr which download client to use for each indexer.

Is this possible?

Not possible, there’s a github item for it though so maybe one day:
