Axapta Security

Hello, we are running Axapta 2.5 (SP2) and have ~ 40 user groups. It’s getting harder and harder to find which group has which permissions on a feature key. Is there a tool / possibility to retrive from a featuer key name , which group has which access level? Where is the security stored? Stupid way would be exporting all group security one by one to excel and then compare is. … THX for help Pirmin
