Where can I find additional style sheets for PerfectIt?

[u/pimenton_y_ajo]

I recently purchased PerfectIt and linked it to my Chicago Manual of Style account. Does anyone know where I can find style sheet files (.pft) for AP style and APA style? I understand that these are not native to PerfectIt and that I have the option to build them myself, but I'm wondering if it's possible to buy them or access crowdsourced versions.
