SMG - Ability for end users to add to their good or bad sender list directly from their spam quarantine

I would like to for end users to be able to add a sender to the good or bad list directly from the spam quarantine list. For example when you select an email from the quarentine list, you should be able to not only release or delete, but also flag as good or bad sender. This is a common feature on many other mail packages.

Thank you.
