Labeling tickets by repository which opened the pull request?

We have a large microservice architecture, and I would very much love to tie all stories to which services were modified automatically.

Is it possible to add a label to any ticket signifying which repository had been linked to the ticket? The goal is that we could then search and analyze JIRA based on those repositories.

The issue describes a desired Jira label based on the repository linked to a pull request, but names no files, tests, or entry points. The repository is marked deprecated and moved to a private repository, so confirm the current implementation location before assessing scope or defining completion criteria.
