Add Bi-weekly feature to custom forwarding rule

Hello,

Can I request a feature to add a "Custom Forwarding Rule" where we can select:
- Bi-weekly => Every second Friday ( or Sat, Sun, Mon)
- Every Second Friday or Sat.Sun,Mon

OF course we can setup it manually with dates range, but this will expire one day and it will be great if we can have this feature to change forwarding rules every second week.
This feature will help to manage "On-Call" schedule for team of people. As for now we need to manually change forwarding phone and as a humans, we often forgot to change it :|

Thanks in advance.
