How to control vr application from desktop?

Is there a way to create an additional window with an interface to control a VR application from your monitor? I’d like to have something like in the Google Earth VR, where you can change some settings, change levels, start an event etc.
I’m using Unreal in architecture design and quite often I make presentations to new people. It would be great to be able to control their experience from “outside” and this way guide them through all the important stuff. If it was possible using blueprints or some plugin, it would be great.
