Is there a way to centrally control Webviewer permissions centrally?

I’d really like to be able to see what models are being used by the Webviewer or not and be able to easily take down obsolete models that are still up there. Even when I go to the “Share” button on a model that I know and can confirm is being shared, it doesn’t show that it’s being shared, it’s the default screen to begin sharing (I have confirmed it’s the right model as attempting to share and then de-share takes down the model on the preexisting URL).

Any way to do this?
