New keys for subscription instead of a permanent key

Hello, everybody,

we have been using the plugin for some time and are very satisfied. But there is one problem: We are selling subscriptions for a software. When the subscription is renewed, the plugin creates a new key. We want the very first key to remain and not to be created again and again.

At the moment we do this by manually deactivating the new keys and manually reactivating the first one. The whole thing looks unprofessional on the outside, as our customers automatically receive a new mail with the new key every month.

Is this feasible?

Many and greetings and many thanks
