Did anybody ever create an app to transfer access rights?

Hi all, my question like said in the topic.
In my project I have about 20 groups and about 80 apps. All groups have the same access rights in the security module except of minor things. So I would need an app that transfers access rights to the groups_apps security table. This would save much manual work.
Did anybody such an app and would share it?

You can do it with a stored procedure you can update the security table.

Thank you alvagar, but I didn’t use this feature by now and don’t know what I can do with procedures.
