Using a Mercurial repo

I am trying to set up Forge deployments using a Mercurial repo on Bitbucket. Unless I missed something, it seems Forge does not support Mercurial from the "Install Repository" dialog. Here is what I'm having to do to get it to work. I'd like to know if there is an easier way.

• Create an empty Git repo and use that to get past the "Install Repository" page.
• Edit the deploy script to change the git pull to hg pull
• On the server, make sure the hgrc file is set up correctly to point to the Hg repo.
• For auto deploys, add the provided deployment trigger url to the repo's webhooks in BitBucket.

Is there an easier way to do this? Any advice is appreciated.
