Can I branch off a branch commit (SHA) instead of the HEAD of a branch in Jira?
I looked over [here](https://community.atlassian.com/t5/Bitbucket-questions/How-to-create-a-branch-from-a-given-commit-in-the-Stash-UI/qaq-p/153097) and [this](https://community.atlassian.com/t5/Git-questions/How-can-I-create-a-branch-in-Sourcetree-git-from-arbitrary/qaq-p/214534) but it doesn't quite have what I want.
We want to create branches in JIRA (because we want to be able to make pull requests easily) but I don't want to branch directly off the HEAD of master. What if I want HEAD~2 of master? This is VERY easy to do in GIT.
