How can I filter / group repo for reporting purposes

Hi, I am currently trying to solve a “reporting” issue. I have been asked to call out all repositories that feed into our production environment. To do this, I need to add some “data point” to each repository so I can subsequently filter for just repo’s labeled “production”.

The only “field” I found that seems like it would work is the “Topics” field in the repository main settings section, but I can not find a way to filter on that field.

Is there any way I can add some “data point” to each repository so I can then either filter from the UI or filter from the API?

I really don’t want to have to use an excel spreadsheet to manually keep track of which repo’s are used for storing / deploying production code.
