make databases available to sync a locked setting

I have DevonPro and love it. I use it all the time. I want my accountants to be able to use it with 1 dedicated computer and fujitsu scanner. The problem is, I want the customer reports put on 1 database and the financial reports put on another. I would like my sales guys to have access to the customer reports on their iPads but can’t give them it right now because the other database shows up for syncing.
It would be great to make this a secure setting that can be locked so that they can only see and sync with the database I allow from their iPads. (all their iPads are locked to prevent youtube, deleting apps, etc.)
