Insert Brush on subD meshes?

I’m trying to use a insert brush on a subD mesh but it’s saying I either need to delete devisions or freeze? I tried freeze but it messed up my geo when I unfreezed it.

What’s the deal here? Am I supposed to just deleted my visions, use the insert brush and hope I don’t need my lower divisions again? I could maybe create a backup clone of that tool, then if needed later I could zremesh and project using the clone?

Clones are good, as well as saved tools along the way.
