How to set to display audio waveform in one track instead of two?

Hi,

I would like have audio waveform displayed in one track instead of two (L and R) in order to keep my Timeline clean. I have tried looking for a solution and couldn't find one, the below post didn't help either:

Can anyone suggest a solution please?

Thanks,
