Pre-filling buy.bitcoin.com address

[Bergerton]

I'm building out a website that will only deal in BCH and I want to make it as easy as possible for people to use their credit cards if they want/need.

Is there anyway to pass a receiving address to the buy.bitcoin.com pages to save them the copy/paste?
I have to imagine there's a get or a post variable I could use - if there isn't, there should be.

Thanks!
