How to pass an event back to FSX after masking it without getting immediate re-trigger?

Hello

Can anyone help me with how to get FSX to process an event that you have masked after you've done what you wanted to do first.

e.g. I'm trapping the NextSubView, in order to do some other things first, but when I subsequently  do this

fsx_simconnect.TransmitClientEvent(DEFINITIONS.Struct1, EVENT_ID.EVENT_NextSubView, 0, hSimconnect.Group1, SIMCONNECT_EVENT_FLAG.GROUPID_IS_PRIORITY)

it re-triggers the event again so I just go around in circles.

The work around I'm using is to remove the event from the notification group, trigger the NextSubView, then add the event back to the group.

Is there a tidier way? I'm sure a lot of Simconnect projects want to do something with events before allowing FSX to process them in the usual manner, so it hardly seems like what I want to do is abnormal.

Thanks for any help
