Domoticz bind extra items thermostat

I have an airconditioning unit that I can control with Domoticz. It has setpoint, temperature, mode (cool, fan, heat, dry) and Fan mode ( auto, low. medium, high) devices but I can only bind the setpoint and temperature device to it. HH can not find the mode devices to bind them. Is this something that should be able to work (in other platforms) or is it work in progress?
