Is there a simple way to freeze the growth of structures when computing harmonic-space power spectra for number count fluctuations with pyCAMB? In other words, the standard output is

with (omitting everything but density for simplicity)

Instead, what I'd like is

Thanks Antony. Yes, you're right, what I wrote doesn't hold in general, but it's the same as saying

where I also allowed for scale-dependence in the bias.
