[Feature Request] Allow configuration of nesting levels in $(branch_name)

[redsigma]

This is related to the COMMIT TEMPLATE section in the configure this repository panel

Currently if i have a nested branch such as feature/Q1/release/TASK-01 , it will use its full name if i type the $(branch_name) in the commit. This doesn't look good if the branch name is very long

I would like to be able to use only TASK-01 or maybe release/TASK-01 as the name

---

For that it would be nice if we can use this syntax:

$(branch_name:1) -> TASK-01
$(branch_name:2) -> release/TASK-01
$(branch_name) -> feature/Q1/release/TASK-01 (same as before no change)

Basically the number is the max nesting level.
