I often use custom direct selects and snapshots to help me see what data is in each scene. What I've found is there is no easy way to come back later and query what palettes are being used. It would be amazing if you could query palettes in a cue range and then get them back in a way that makes it easy to drop them onto a direct select. You could do this in a way such as:
Query Color Palettes in Cue x Thru x
This would get the Color Palettes that channels have in the cues, tracked or move to's. Then you could do
Query Color Palettes in Cue x Thru x Cue Only
To get only the move to's and ignore tracked color palettes.
