Plugin for variable custom EQ

I’m looking for an Audacity equalizer plugin that will show a number of equally-spaced bands to tweak, but let me chose the high and low frequency. For example: Instead of a plugin window showing 15 bands between 20 and 20,000 Hz, it would offer 15 bands but allow me to specify a range between 160 and 640 Hz.

Is there such an animal out there, and where do I find it? Thanks in advance!
