It's common for Github repos to use a standardized branch naming convention, and is typically considered a best practice (https://dev.to/jps27cse/github-branching-name-best-practices-49ei).

Currently the Github integration "Create Branches and Pull Requests" feature only allows setting the suggested branch name with only: :taskId:, :taskName:, or :username:.

I find it helpful to use custom task type and would also like that to be an option in the branch naming convention.
