Multiple payment plans tied to same Subscription

Hello Support.

How would I set up the Subscriptions if I wanted 2 time frames for payments (monthly and yearly) and three different Subscription Plans: Gold, Silver and Bronze..?? Would I have SIX subscription plans?

That seems confusing as there will be six boxes on my Registration page. Or can I somehow combine the monthly and yearly options inside each of the three subscriptions..?? That way I will have 3 actual boxes on my Registration page with the two monthly/yearly options inside each of the three boxes.

Can you please guide me as to how I can achieve this through custom shortcodes...?

Thanx in advance.
