Subscription for the variable product

Hi,

Does this plugin supports subscription for the variable product? e.g. right now, for a simple subscription (your demo), i can have a product that charges user a weekly fee, but it is an individual product. However, I want to see a single product with select options so that User should be able to select ‘Monthly’ or ‘Weekly’ subscription. I can display select options for the variable product but then how do i enable subscription function for it?
