Hi, i can build you a plugin to provide this feature. However, the control page will be a separate page than your current formidable form builder page.
There will be a new page, where you will have a dropdown to select and form, and then select a combo field (select, radio, checkbox). After selection, the values will appear with the visibility controls. So you set the control, and save it there. If you want to change multiple field options, you can select & save one by one.
On the frontend, the filter will be applied based on your selected role based visibility restriction.
Does that sounds good for you ?
