Record a safety track with a single microphone

With a UR44 - how can I record a safety track ?
With a single phantom powered studio microphone sometimes you can get clipping or maybe the signal is too low and the S/N is not good enough. A standard practice is sometimes to record two tracks simultaneously. The main one and another track with a 10db attenuation.
Can I set the internal interface to take the audio from one input and pass it to a second input ?
