basically what I’m suggesting is you could try something “under the hood”, from the database and file system. But maybe it’s difficult for you.
I’m sorry, but if the user interface can’t do it, and you can’t go down to code or to the database to do it, it’s hard to help… Maybe try to hire someone for a quick project?
There’s a company called Urdhva Tech which makes nice add-ons for SuiteCRM and their developer usually frequents these forums. They make projects and consulting.
For bigger projects I would recommend talking also with SalesAgility themselves.
