Tasmota on Shelly Dimmer2 - can I use the two switch inputs for different outputs in HA?

I have a Shelly Dimmer2 flashed with Tasmota. It has two 'switch' inputs. I have the shelly installed behind a two-gang switch box with the two inputs connected to two different switches. But currently, if I flip either switch, the same light is flipped (the one connected to the output of the Shelly Dimmer)...
