Custom customer name for online purchases

[UTUBookstore]

I'd love an option for customers to include a name that is not the name on their credit card/payment option for online purchases. I understand this might be a minefield for identity theft, but a lot of our customers are nonbinary and trans and are required to use their deadnames on their payment information, which leads us to deadname them because it's the only name they are able to offer us for online purchases.
