This option enables creating pull request when pushed commits have message that matches regular expression (also configurable - see image above).
Regular expression matching group TOBRANCH is needed - it describes target branch to create pull request to.

This options enables adding reviewers from commit messages pushed to Stash. Reviewers are taken from regular expression matching group REVIEWERS. 
Warning: this option works only when New pull request from commit option is also enabled.
