Is it possible to wire a receptacle so that a switch turns both inputs on.
That is, I know how to wire it so one of the inputs it tied to the switch.
But is there a way to tie both of the inputs to the switch?

Unless I'm completely missing the point of the question., just leave the jumper
/ tab between the top and bottom outlets in place, and both will be energized
automagically.
