Rent to own pay remainder full option

It would be cool to have an option for customers to pay the remainder of their renter-own subscription. Right now, it is set up with milestones, but with renter-own being a very popular thing in VST plugins, it would be cool if customers had their own little dashboard where they see their progress and where they can choose to pay the full remainder. This would also make it possible to market towards them and upsell them into paying the full remainder possibly even with a little incentive, like offering them another product discount or something for free, pulling cash forward for the moon base user and allowing customers that want to pay it off.
