Pulseaudio won't allow simultaneous input/output for USB headset mic

The audio profiles available when using my Logi USB headset mic can make the device appear as an input or an output but never both at the same time.

I have tried investigating custom pulseaudio profiles and messing with udev rules but I fear I'm out of my depth here.
