Family Sharing Payment Method Changing

Hello,

I am a member of an Apple Family, but I highly dislike being tied down by the family organizer's payment method of choice being my only option to use in the App store since I don't want my dad's card to be charged for my purchase of some editing software. Is there a way for me to add my own payment method(credit and debit cards) without having to leave the family or anything of the sort?
