As an staff user, I would like to set a default repository for login

When there are multiple repositories, and a user has access to more than one of the repositories, the default repository in the Select Repository box is whichever repository is first numerically based on repository ID. The ability to set a default repository to be selected upon start up would save some time.

Would this be a setting the systems administrator sets for the entire instance, or something that an archives supervisor sets when setting up a user's account? What would this look like and where would this setting be found? It's a good idea, I am just curious to get more information. Thanks!
