Split paying!

So, google gave me a 40 NOK gift into my google account since I have Google One, I want to use it to buy Nitro Classic. Imagine you have a gift card with 4 dollars, you want to use the gift card and the rest from another account. There should be a button that says "Pay twice" then you select how much you want to pay at once, then you can choose what to pay with on the first, then another tab will pop up in the discord app, and there you pay the rest, from another card.
