Monthly boosting with a yearly subscription

Please, for the love of god its been years since I've seen responses to posts regarding the differences between monthly and yearly subscriptions and so far the only changes to nitro we've seen are giving people who pay 5$ more enough perks to make the nitro classic useless. We really want to be able to buy monthly boosts with a yearly account, instead of paying another 50$ to boost a server which we may only want to boost once. Also with this, it would be nice to be able to swap a yearly subscription to a monthly one that just gives you credit for how every many months it is. Please, enact this change as it will make nitro so much more worth it!
