WooCommerce Subscriptions

It would be great if you could develop an extension that allows for product price increases on existing subscriptions (i.e. we have 10 membership fee products, and the fee for each of those goes up annually. Under the present system, if I increase product costs those increases aren’t picked up on existing subscriptions when they renew the increases only come into play when someone takes out a new subscriptions. Currently, if a member takes out an annual subscription for say $300 they will be charged that $300 for as many years as they have the membership. We want to be able to increase the membership fees, across the board, annually, and have current subscriptions charged the increased price when they renew.

Thanks Woo Team:-)
