How to use a retractive switch with a Somfy blind

I want to buy 4 Somfy blinds, and connect them with RTS. However, I don’t want 4 of these:

Instead, I want this:

Where each switch is a 3 position retractive switch. Up, down, and off.

I know I could wire this in directly, which would involve chasing the walls and pulling up floorboards. However is there an easier wireless way I can do this with ST? Maybe with a controller somehow?

I know Somfy offer a handheld 16 channel controller, but I want old fashioned physical wall switches.
