Hi
If the cue exists (and maybe is empty) I would simply playback the cue and update it with the look I want, using "Update". If the cue don't exists, and I want it between for example cue 44 and 45 I would simply record a new cue 44.5: Type record and use a keyboard to type in 44.5 and click the cue-stack. If you don't have a keyboard connected you can press "Z/shift" and type 44.5 using the Syntax. If you don't like having a cue 44.5 you can go into advanced playback settings and renumber your cue-stack. Please note that you have to take into consideration tracking-options when you update or insert at new cue into a existing cue-stack. Also, if the look you want exist in a existing cue and you want to record it into a cue in another cue-stack, I think you need to record the cue using Smart Tag or else nothing will be recorded.
Maybe this can be useful when using tracking:
Kind Regards droiddk
