[Fix 11.2.1]Triggering a cue "xx.xx before end of" a sub-cue

[d_korman]

Not sure if this is a bug or intentional. When you set a cue to autostart xx.xx before end of a preceding cue, and that preceding cue comprises multiple sub cues of different lengths, the autostart cue triggers xx.xx before the end of the FIRST sub-cue, not the LONGEST subcue. I think it should either trigger xx.xx before the end of the longest subcue, or, ideally, it should be possible so select a specific sub-cue in the cue selection drop-down.

It's a bug. Fix ready for 11.2.
