you can do this with another trick:
creat a stereo group and invert the phase.
put a sidechain-gate in the group and put the bass in the sidechain of the gate, so the gate opens when the bass is playing.
now put an e.q. in the group with a lowpass around 100hz (put the e.q. after the gate, and experiment with the cutoff of the lowpass and also the slope).
now send everything (sending, not routing!!) to the group where you wanna kill the lows when the bass is playing @ 0db (when you don't want to kill the lows completely, try to send it with lower levels like -3db to -6db etc.).
have phun!!
