ADAU1467 - custom Sigma Studio modules

I've seen this question asked but not properly answered.

I need to move away from a deprecated DSP for our custom surround sound algorithm, and while the ADAU1467 looks suitable, there are a couple of things not available as modules that I need. But I can't use a third party to create them as it's proprietary, so using Base10labs isn't an option. I have done custom dsp assembly for other DSPs.

Is there any way to do this with this DSP or am I stuck looking elsewhere?

Cheers
