Once a user has clicked an appointment to select it, I'd like the ability to clear this selection. For example, if you show one set of appointments, then click a radio button on the page to switch to a different set of appointments, I'd like to clear the selection so that no appointment is selected. The way it works now, the component appears to store the index of the selected appointment and then re-apply that when it's rendered with new appointments.
