Share a view with externals without needing to add them manually

[Luuk]

I would like to share a view with externals without needing to add them manually.

Is this already possible or not? Just share it to everyone with the URL basically. Now I would need all my customers manually first which is undoable.

Ideally it would be great if we could add an email domain and give that permissions to the view.  Then we retain some control over who can access the view, but don't have to add loads of individual email addresses.
