I'd go for the playback option then because these are like scenes in a show and you probably want to fade between them. Set up a playback with the 4 cues in it as if it was a show with fade times. You only need the 4 cues. Then go to setup/triggers and set the 1st 4 remote switches to execute a cue each. Test it from a USB keyboard using Ctrl/F1 to Ctrl/F4 including going from "show" to "doors open/interval" and FUF to "doors open/interval". Job's a good 'un (hopefully)

Me too because the UDKs can all be active at the same time but cues in a playback "replace" each other. Does depend on what you are trying to achieve though and you might need to dedicate one switch to releasing the playback.
