Radarr

Seeing as the only place I found this was on "the place that shall not be named" before the black out, I hope this question can help start the new repository of collective knowledge here in the Fediverse.

I have set up a separate instance or radarr to maintain copies of RiffTrax. The two main questions I have that I can not find answers for on trash's guide or elsewhere, is setting up a custom format that will pull files with "rifftrax" in the title. I found in trash's guide how to exclude with

      {
      "name": "RiffTrax",
      "implementation": "ReleaseGroupSpecification",
      "negate": false,
      "required": false,
      "fields": {
        "value": "^(Rifftrax)$"
      }

and I have been able to create a custom filter that helps when manually searching.

I have two questions:

1. how to modify the above to help me?

2. how do I use my current library on my main radarr instance to help the RiffTrax instance search and pull movies? If that is even possible.
