Appointments+ UX Question: Paying for Pending Appointments

Hi There,
After reading through the shortcodes docs I realized that pending appointments don't show by default on the my-appointments page (a UX fail IMHO)
So I changed the default shortcode to [app_my_appointments allow_cancel="1" status="paid, confirmed, pending, completed, reserved"]
But now I noticed an issue: There's no button in the My_appointments table for users to easily pay for a pending appointment.
