First of all. Thank you for this project.

It would be very nice if the output format would be configurable. For example:

* [Issue #942](https://github.com/resilience4j/resilience4j/issues/942): Introduced new CB metric "notPermittedCalls"

  sections:
    - title: "Enhancements"
      labels: ["enhancement"]
      format: "Issue ${issue_number}: ${issue_title}"
    - title: "Bugs"
      labels: ["bug"]
      format: "Issue ${issue_number}: ${issue_title}"
