Hi, I'm super new to Phabricator and also new here, so apologies in advance if this is the wrong mechanism for this request... "Give Feedback! Get Support!" seemed to be sending me here...
Currently arc land supports the ability to specify a remote name that is not "origin", but there doesn't appear to be a corresponding configuration setting.
Since I wanted this functionality for my use, I forked arc on github and added a configuration setting for this (and it seems to work). Would you be open to getting a pull request for this?
