How can I display a widget as filled radio Buttons in the global map?

Question

I know that  displayAs: #radioButtons  will generate those smaller radio buttons if I use them in the global map, but how about widget types such as radio buttons (fill) or even just toggle (fill)  ?

Is it #radioButtonsFill by any chance?

Also whilst we are here, can I also specify  default VCS On and Off colours for button type widgets in the global map or in a paramater transformer?

Thanks!
