Blackout, electric, remote blinds that mount in WALL (1 Viewer)

[Hogarth]

I have a home theater with strange windows. They have no room to mount 'typical' blinds on the frame or side-jam so I was hoping to find a blind that count mount in the wall itself a bit outside the window trim, on the actual wall and have any track hidden by curtails. I have looked for a blind like this but not found one anywhere. All the blinds I have seen mount on the window jam. Is anyone familiar with a product that will do the job I am describing? Thanks.
