Lowpass/Highpass in Wave Shifter

Just like what Cluster Delay, Flex Chorus, and Swarm Reverb have, some simple lowpass/highpass knobs added to Wave Shifter would be helpful for confining the effect to only the frequency range you need. For example, I’ve used Wave Shifter for bass sound design pretty often, but I don’t want the effect to interfere with the sub or even the low-mids in some cases. Simple lowpass/highpass knobs would easily suffice for this.
