If you need to control both top and bottom on some outlets that are all on the same circuit you could wire in a XPFM at or near the breaker box (the beginning of the circuit). The XPFM is rated for 15 amps, non-dimming, inductive or resistive loads. This would control "ALL" the outlets on that circuit but would not give you independent control of each one.
This is just a suggestion if you have a few outlets that don't need independent control and your total load for the circuit doesn't exceed 15 amps.
