Ability to set up a custom billing date for all subscriptions for my ecommerce store. I have a subscription product that needs to charge on the 15th of each month, however look like it's not possible yet to set up a monthly subscription where your customers will be charged every 15th (or whatever the custom date is) of each month. This is because the subscription currently works based on the time they've purchased the subscription product.
We have a box of the month club that ships out on a particular date and depending on when the product was purchased would determine what month they start their subscription box on. So, we need the ability to not just have it bill on a certain date, but also push off billing to the next months billing cycle too.
