Select ExecRunner in .drone.yml

Hi there,

I really felt into love with drone and now trying to add my raspberry pi as a exec runner for automatically deploying some of my services.

I am wondering if it is possible to specify the exec runner that should be used for a repository.
I know I can specify the repositories the exec runner will act on. Does this mean, I have to configure it the way that only the exec runner(s) listen on the repos I want to have the deployment at? What would I do if I have more than one deployment?

Thanks a lot.
