It turns out you can do this with Google Forms and it’s actually pretty easy. I made a tool to help you convert your links.

Keep in mind that you need to know to generate pre-filled links with Google Forms before you can convert it to a single-click URL.

Hope this is helpful! Let me know if you have any questions or suggestions.
