The best way to program complex shows is through the use of pallets.
For example, if you have a number of cues that need to focus movers on the singer, centre stage. As you say, editing every single cue before showtime is seriously tedious.
Instead, create a single palette that ONLY sets Pan/Tilt values for the movers. Then, drag that palette into every cue that needs to focus movers on the singer.
Now, before each show, you only need to edit Pan/Tilt values in your palette. Every cue & cuelist referencing that palette will automatically use the new positions.
