Membership Plugin & the "Require invite code" feature

I would LOVE to see the "Require invite code" implemented on a subscription by subscription basis.

1. The ability to turn "Require Invite Codes" on and off on for each subscription level.

2. The ability to have a single reusable invite code for the lower level subscriptions and individual codes for the higher level subscriptions.

hoping the holiday season finds you well,

Ian
