Variant "Group"

I'm having a massive issues that I need to resolve… ultimately, I can solve it by using variants… HOWEVER, the UI really needs to be tampered with. The way to do this is to somehow be able to “group” variants. Without a group, each products variants would end up being a massive page that scrolls and scrolls.

Does anyone know if there is any way to accomplish this with a plugin or even modifying the code?

It's my only hope…
