Allow the use of regex instead of needing to match exact comment name

[stephansama]

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and discussions and couldn’t find anything (or linked relevant results below)

Problem

When using the plugin you have to match on the exact comment title. It would be nice to allow a looser search allowing the use of extra comment metadata for plugins

Current solutions

I created a patch file for my usage

Proposed solutions

I created a pr addressing the request.
