Keep a folder within box sync'd for an integration

We have a service with a Box integration that users access to keep certain company docs on mobile devices up to date. These docs appear in various other folders within our Box account. Up to now, when one of these docs gets updated by someone in the company, I copy it into the sync folder for the integration. Is there a way to make those files in the sync folder a link to other Box files/folders instead of manually copying them every time there is an update? It would also reduce how much storage is required as we wouldn't need two copies in the account.
