Make out of stock products selectables (variation swatches)

I there, I just bough your support in envato market but it seems that it doesn’t get actualized instantly.
I wanted to ask for the same thing as that guy here : https://villatheme.com/supports/topic/make-out-of-stock-products-selectable/
Could you please add that function, to make out of stock products selectables ? I need that for getting more precise stock requests for clothing sizes.
Thanks in advance !
