Campaign buttons + mission selection enhancements

I want to request a possibility of using both of these features simultaneously. Mission selection was accessible through additional menu button in the screen with campaign buttons in NPSE.

Why? Because I want to request a possiblity of a mission to appear in the "Mission Selection" screen after it's been completed for the first time, although I understand that this would require working save/load function etc.

Also, possiblity to have both of them would make it easier to have "main campaigns" (accessible through buttons) and bonus missions, provided after the mod release.
