I am very interested in the ability to set custom templates for commit messages and PR titles. We have a requirement to put a JIRA ticket number in both of these places.

I'm also interested in this; seems like a relatively small change too!

Rebased to incorporate new changes on master and fix conflicts.

Heya, what needs done to get this functionality added? This still remains a dealbreaker of using this tool for us.

We are very interested in having custom commit messages, as we are using conventional commits to automatically set our version.

We are able to invest time into this feature. How to go on with this PR? What's missing? How can we help?

[msallin]

Any news? Still ready to help, if necessary.
