Custom In-Editor Tutorials

I’ve been working on an idea of creating a series of tutorials for UE4, and I was trying to see if there was anyway to create the In-Editor Tutorials that the Engine already supports. There are mentions of this inside the MediaPlayer but appears to have no concept actually applied.

I was just curious if this is possible now, or in the near-future in any way?

Hi, have you find how to customize tutorials?
