Customize create pr prefilled name

**Is your feature request related to a problem? Please describe.**
Currently when you create a pr, it takes the branch name, capitalizes the first letter, and replaces underscores with spaces(At least thats what it does in my usecase).
 
**Describe the solution you'd like**
I would like the prefilled name to be to keep the branch name, unmodified.

**Describe alternatives you've considered**
Looking in Config.md for a template variable.

**Additional context**
