Long time lurker, but just wanted to chime in on this one.

Not necessarily I suppose a maneuver, but for what you described, I'd just treat it as a single-action block against multiple people (allowed by YS 210 Resolving Blocks).

So like grease might be a block against movement as everyone falls on their butts.

Slow time might be block against attacks (though it'd be odd that they could move out of the zone, but not attack out of it).

The point is though, with a block you can lock down either all action on a single target or a specific sort of action on multiples.

If you're looking to lay aspects on people, then ignore this and go with what DFJunkie suggested. If just locking them down, then I think this would be simpler.
