Radio button or yes/no custom field

I’m using 3.8.1. Is there any way to create a checkbox or a yes/no custom
field with a default to ‘no’?

“Select one value” doesn’t do it as it always presents a third choice '-'
and the window is 5 lines.

The autocomplete doesn’t quite do it.

I just need a checkbox to flag a ticket a certain way.

Never mind; found the extension right after I posted.
