In the parameter queries, I can't find a way (based on the documentation) for the 'selected' option of a radio button list. I see there is one for select lists (selected) and for checkboxes it is the fourth variable as 'checked' - but the radio button documentation at https://mydbr.com/doc/content/start.userparam.html#par-radio seems to indicate no pre-checked option is possible. Is there a way to do this?
Related to this, is there a way so that with a radio button list as a parameter query, NO option is preselected/default? Right now, the first option is unless I put in a 'none' option first, and I'd prefer to have them all unselected by default.
