I would like to wish for a “pay now” feature on the subscription.
In some cases you want to pay earlier than your yearly payment renewal date.
Reason might be due to weekend, salary, vacations etc.
So in essence, there should be an option to “pay now” in order for the charge to be executed.
In order to keep our subscriptions at least cost, we have simplified and automated our options. Your suggestion would add to the complexity and therefore the potential cost of subscriptions, which I doubt users would want.
