Communication Center-permission to delete fax

The ability to delete a fax from the communication center should be permission based. I would like to see more granular permissions on the communication center in general, it should not allow all the users who have access to delete a message/fax, forward, print, or scan. Each of those permissions should be user/role specific. But most importantly, the ability to delete. If a whole group of people are working off the faxed document and someone deletes it that shouldn't, that will cause some difficulty in retrieving it. Also the ability for it to go to an "archive" or "trash" and be stored for 30 days before permanent deletion from the CPSI communication center would be good too.
