Suitcase Fusion - Making A Font Set Within Another Font Set?

To AppleScript wizards

I’ve been wondering if it is possible for Suitcase Fusion to make a new font set within another font set? Or, moving a bunch of font sets to a different font set would give the result I want.

I tried the ‘move Font Set “A” to Font Set “B”’ command but it made only the alias of Font Set “A” within Font Set “B”, leaving Font Set “A” at the original location.

I also tried 'make new Font Set at Font Set “B” with properties {name: “A”}, but this was simply denied as a bad grammar.

So, what am I missing?
