It would great to say event for gateways . Specially the event for the get marchent and non marchent gateways .

The events we need is not only send the result query to the trigger, but to listen to the returned list and provide it as final result . A exemple .

The available nonmarchent function send the gateway list to the event . Then it listen to the event if it return a data , if yes return it if not return the first list . With such event i can do the fallowing .

Show gateways based on client groups
Show gateways based in clients countries
Show gateways based in clients service count (first order like exemple)
And so many other critirea ..
