I'm not understanding what you are asking here.
the L358 allows you to trigger your PW remotely. but you can just use a wireless remote like the Canon RC-6 to trigger the camera shutter (which in turn would trigger the flashes).
I don't see a huge need for the wireless option the L358 offers. especially given the hassle involved in plugging them into the PW Utility to change them over to standard channel. I'd rather just keep them in TL mode and trigger my shutter wirelessly...
