There is a repo hosted on 3rd party machine.
The phabricator server has its write access to the 3rd repo host, and all other phabricator users only have read access.
Once a patch is reviewed and ready to land, the user can't do it because he/she has only read access to the host repo.
In such case, is it possible the user use phabricator to push the patch to the repo? How?
