Radio buttons are very useful, it would be even better if we could choose their format.

Specifically I would like to be able to select if Radio Buttons are:

• Circles
• Squares
• Xs
• Checks

One example is section 3 of a W-9, a document that is widely used in Pandadoc. This is the perfect use case for Radio Buttons since the recipient should only select one option. However, W-9s have square boxes usually meant to be checked. A filled in circle works well, a check would be better.
