Flight plan: save and load "AutoWP" mission with all data

Hi Michael, it would be interesting to be able to save and load "AutoWP" mission so that we can load and edit without having to recreate it again all the time.
When loading an AutoWP mission saved is expected to open the window "Survey (Grid)" with all the settings stored in the saved file above, so that if I want to change only one parameter can save it for future use.
I mean not only the wp, cam and other mission event but all the data in the "Survey (Grid) section.
For example a "load/save" option inside all the "AutoWP" section.

Start by locating the AutoWP section and its "Survey (Grid)" window in Mission Planner. Trace how mission events and survey settings are currently created, then define a save/load path that preserves all Survey (Grid) data and reopens the window with those settings restored.
