Multiple Products Per Subscription

We need the ability to add multiple products when creating a subscription.

Stripe has this capability.

Use Case: We offer several options for clients, add on, cross-sells, etc. and it would be way more convenient to add multiple products when creating the subscription, rather than having to create a subscription for each product.

This enhancement goes hand-in-hand with the ability to edit a subscription, as there are times where we would need to cancel/remove a particular product and/or add an additional product to a subscription.
