Constant Quality and 2-pass encoding

Why is there no option for 2-pass encoding when using constant quality?

Because the two are fundamentally incompatible. Constant Quality doesn't need to know what the whole video will be like since it just targets a specific quality, so it doesn't need a first pass.
