Jira Tickets and Stash

I have 2 questions:

When my users commit to a Stash/Git repo using a Jira Issue number for tracking, the commit history only shows up if they write out the Jira Issue number exactly as it is in Jira...for example, FAST-1231. Can we somehow set it up so that this is not case sensitive?

When users create a branch from a Jira issue, the branch gets named after the Issue # and the title of the issue - "feature/IT-14-updating-submodules-to-php4.3" Ovbiously we can delete the "updating-submodules-to-php4.3" postion, but it would be far more ocnvenient if these branches would default to just being named after the Issue # alone. Can that be done?

Let me know, thanks!
