The Lighting Controller

I’m running Showxpress and I made a light scene with my artfox7rs and I didn’t add all of the lights dmx channels we are running with these lights. Like I’m running 16 7rs all on their own Dmx channels and I want to add the ones I forgot during the building of the scene

I created some new scenes and forgot to add a couple of our fixtures in the group. Is there anyway to add new fixtures to an existing scene without changing dmx channels on the fixtures
