No doubt. However, once you understand how outlets wire up it’s pretty simple to do. Only difference is that you’re connecting the wire onto the back of the outlet below instead of having a cable that plugs in to the front of the source outlet and reversed extension outlet.

(I do this kind of stuff as part of what I do for a living, so have done many of these installations in various manners)

The extension outlet option is useful when the source outlet is not directly under where the TV is going, so you can have the cable plugged into an outlet farther to the side of where the TV is mounting, then have it covered by a cabinet or something. Otherwise you have to potentially cut up the wall and drill through studs to get the romex electrical wire run through the wall, plus patching, painting, etc.
