I use the method ericepv mentioned. Made my own screen panel. Recently had to also add cable railing and did that as a furred wall and overlapped it with the screen wall. Worked well. Railing is weird with doors though, so if I add a screen door, I have to insert my screen panel manually as millwork above the door and resize it to fit. Not too big of an issue, I just have to remember to move that panel if I relocate the door. I suppose I could make a panel that includes screen, a top rail, and cable if I remember.
