Replacing screens on a screened porch

[fred1949]

Does anyone have a simple way of replacing screens on a screened in porch? The screens I now have are installed in a spline on the outside of my porch. My yard drops off drastically which makes getting to the screen a long way up. I've been trying to think of a system I could install that would have the screen on the outside of the structure but one that could be fixed from inside the screened in porch. Let me know your thoughts.

Thank you,
Fred
