title: Use email alisas for commit message in Bitbucket
body: <p>I have a personal email address to log in to Bitbucket and I have an alias - my work email.</p>
  
  <p>When I create a commit and push it into a remote repo the commit has my alias email as an author (done by .hgrc in a local repository). However, when I create a commit (or a merge) by web UI the author is my personal email.</p>
  
  <p>So, I'm wondering, is it possible to use a specific email alias for a particular repository? In other words, I want to sign in with my personal email (or with a Google account) but use my work email for certain repositories.</p>
