Common Source N-Channel JFET 'Fat' Control

Is there a way to variably alter the frequency response of an N-Channel JFET amplification stage with a pot instead of a toggle for the source capacitor? I'd like to keep the gain static and not disrupt the Vgs bias voltage in the process.
 
Yeah, I’d imagine a cap blend pot on the gate would be a faster route to a similar destination.
 
I was hoping to avoid adding another gain stage if possible, but I should be able to do that without being too lossy. I was curious if there was an obvious way that I was missing with the source cap.
