Edward was referring to the 3rd option in the poll - "Discrete timings on FLX (apply specific timings to specific parameters)" - so if this is a feature that you'd like to see, vote for that one
Yes, they run as two completely independent cues, just at the same time rather than after each other. It's the equivalent of "Part Cues" on other consoles (when I use them, I have my first cue as Cue X, and then use point cues for the Auto-With cues, so Cue X.1, Cue X.2 etc). Just make sure you don't tag the same parameters in both cues (and definitely don't use snapshot!).
