All-Pass Filters?

Hi,

I was hoping to find an all-pass filter in Pro-Q2 for x-over design purposes. Is this (rather important) feature missing?

As far as I know, it is. (Missing)

Biquad / Linkwitz Transform ?

I suppose you could use a shelving lowpass + notch to mimic a LT but it is a real shame these features are missing; in particular the phase adjustment through the all-pass filter is essential for proper x-over functionality.
