Create nested group within a variant component

A set of variant components (checkboxes) has already been created. However, I want to add another nested grouping within each variant. Is there a way to do that without deleting the variant and starting over?

I recreated the scenario you described and was able to do this by selecting the instances you want to group and just doing it the normal way (Command + G for a group or Command + Option + G for a frame). If that doesn’t work there might be something else going on.

Forgot to mention - Is there a way to group it as an instance? An example below with “Checkbox” instance group
