Is there any way to change the default commit message for pull requests merged via Bitbucket? When I click "Merge" button on top of a pull request page, the resulting commit has a default message like

    Merged in some-branch (pull request #25)


The problem is the fragment `#25` because I often push the same repository also to Github which links the number to the issue no. 25. I know that there is a text area where I can edit the message before each merge but it's really hard to remember.
