Show inteface on menu screen?

Is this possible? Or are interfaces always coupled to a character (and characters can not be a part of menu screens)?

There's an option inside of the interfaces properties tab: "always show interface" - something like that. The interface still needs to be linked to a character mind, but it will always be displayed unless manually hidden.

I used the option for my main control interface in which I added some black bars to the top & bottom of the screen for a more cinematic feel - also they were useful as they gave us somewhere to display spoken, narration & action texts.
