Volume control for stereo signal?

Hello all,

Let's say I have two mono sources that will be outputted as a stereo
signal to a headphone. If the mono sources pass thru two simple opamp
configured as inverting amplifiers, how do I control the amplitude
level of both mono sources simultaneoulsy? Is there a potentiometer
that has multiple variable resistors that can be controlled by one
knob?

Thanks!
