Add custom payment link#88

Many payment gateways (of national banks) have the characteristic of generating payment links for individual services, very useful for freelancers. This would allow me to connect my national gateway (wompi, El Salvador) to receive payments directly to my bank account.

What a thrill to see this message 🤗 greetings 🇸🇻

This is definitely needed.

Include the ability to add links, images & QR Codes to a Custom Payment Option. OR the ability to edit the On-Site Payment Option to be customized to ad/inclde images & links.
