Pick list members based on PR information

Is your feature request related to a problem? Please describe.
Not exactly a problem. Could be an improvement for the (already awesome) tool.
The idea is to have a way that we could select reviewers from one list or another based on information in the PR.

Describe the solution you'd like
Let's say we have two reviewers lists:

• Frontend (F)
• Backend (B)

I wanna pick a reviewer from the list F WHEN my PR title has [FRONT] tag and pick a reviewer from the other list (B) when we have [BACK] in the PR title.

Describe alternatives you've considered
I don't know if this is possible. I'm starting to dig into this and if I find something I'll be happy to contribute.

Additional context
Nothing to add
