Paperless and restricting GL accounts

In Sage paperless, is there a way to restrict certain GL accounts from being used? Or what if under set up index type, rather than bridging to the GL, you input only the specific GL codes that should be used in paperless? Would that work? Since the GL code you input on the index matches to the GL, it would still transfer to the correct specified Sage 300 CRE GL account, right? You don't necessarily have to have the entire GL bridged do you?
