Ability to separate charges from rate plans so that bundles can be created when subscribing.

As a merchant, I would like to be able to pick and choose charges to add to my subscription when a customer is subscribing. It is not currently possible to create  standalone charges (without a rate plan), or to add / remove charges to a product rate plan when subscribing.
