Move existing groups within variables collections

I would like to be able to move existing groups within collections in variables.

e.g. i’ve created group ‘paddings’ and realised later that i’d like to move it into a different collection (from ‘brand’ to ‘responsive’). At the moment I have to manually re-enter all the values. Pain in the butt if you don’t get your design system right at first go.

I would like to be able to just drag and drop.
