Multiple usernames for a VCS root

Hi

I've just noticed that when my GitHub settings are set to anonymize my email, i.e. my email is replaced by <GITHUB_USERNAME>@users.noreply.github.com (see https://help.github.com/articles/keeping-your-email-address-private), then TeamCity cannot determine that I was the user performing certain actions because the VCS name is different. So now I'm wondeirng if it is possible to assign multiple usernames to a VCS root?
