D6 Payments - Automated reminders and not interested

D6 Payments - Automated reminders and not interested

Hello

Please could you consider adding functionally to d6 Payments that could do the following:
1.  Reminder end uses to make payment
      1.a. Administrators to set when the reminders go out.
2.  Give end user the option do indicate they are not attending/not interested so that they don't get the reminders.

Karri app has this funcationality.

Thank you.
