Does anyone know how to link Creator Users to CRM Users, or get a list of CRM users in Creator.

We are creating Sales Orders from our creator app, and one of the things we want to do is set the owner. Is there anyway to get a list of users from the CRM - without needing to hard code a connection name. Or to link the two together?
