Application Server Rest Api permission to trigger just a single event type

Hello,

i want to create a system user which can only fire a single event for an entity.

I tried to use a program function with a link to the event and assigned this program function to the permission group of the system user.

It seems not to working unless i add the programm function "Common_TriggerEvents". But with this function the user can trigger any event.

Is it possible to just allow the triggering of a single event type?
