Radio Button Filter Card - Set the default selection?


I have a Radio Button Filter Card on my page. I'd like a default value to be selected on this card. However, I can't seem to find a property that enables that.

When i use Page filters to set a default selection the user can clear the filter, or filter on multiple values (which defeats the purpose of the Radio Button Filter Card, the data only makes sense if a single value is filtered on).

Any advice?
