How to change shape of all button variations in a UI kit?

Hi. I searched but didn’t see anything addressing this, though I’m sure there must be…

I’m using the Material Design Figma UI kit. I want to change the corner radius of all buttons in the kit. The only way I can see to do that is to select every variant inside the button master component container and type in the new radius. But there must be a better way of doing it.

So: How would I go making a change to corners, lines, whatever in a master component and having that propagate to all variants?

Thanks for any help.
