best uses for Soup Grabs?

[Birdo!]

I've been labbing with tech trying to optimize my Fiona since I have been kinda out of touch, and I was curious what soup-grabbing adds to Fiona's repertoire.
soup grab anti air obviously is a pretty good way to set up a slam, and it seems to not activate the slam pushback as often as shield-cancelled grab into Anti-Air, making it a little more reliable (in my experience) for getting guaranteed OTG slams. I might be wrong tho, I wasn't testing it in debug mode or anything like that.
Can the opponent break out of a soup-grabbed dash attack while its happening, cause if not it could be used to carry an opponent somewhere on the map (like a fireplace) and then quickly throw them in.
Sorry if I'm wrong about anything and seem like an idiot

Soup grabbing is almost useless for Fiona. Her goal is to get air dashes which she can get out of a grab release so there's really no point. She can get an air dash out of an aerial soup grab, though, which is very useful.
