Option to hide pages

It would nice to hide pages so that they only appear when editing them and not through the web interface…

This may seem like a strange request… but by doing so you could have pages that are used for casting only…
At the moment I have a “Master Control”, “Living Room Control”, and “Kitchen Control” pages…
I want the “Master Control” to be the only one visible in the web interface … but when I ask Google to “Turn on control in kitchen” I want to have the “Kitchen Control” page show (effectively a subset of controls in “Master Control”).
