Replacement character for space in branch name - change to "-"?

Hey,

When you create a git branch in WebStorm, and you type a space whilst entering the branch name, WebStorm helpfully inserts and understore ("_") instead, since spaces are verboten in branch names.  However, my team would rather the space be replaced by a dash ("-").  Is this something you can customize in WebStorm?  I looked for a setting but did not find one.

Thanks!

Eric
