Multiband Dry / Wet control for Sonarworks 5?

A multiband Dry / Wet control would take Sonarworks to the next level. I think 3 bands would suffice. Adjustable in frequency, if possible.

Why? Most of us have project studio's where the limited room size causes problem in LF frequencies. After some basic acoustic treatment (first reflections), we have less problems in HF, where the character of our loudspeakers resides. I would like to retain some of the intended HF character of my high end-ish monitor speakers. 

Ideally, I would like to set the "effect" of Sonarwarks like this: 

<300Hz - 100% wet
300Hz to 5kHz - ~75% wet
5kHz to 20kHz - ~40% wet

Just a throught! :)
