Hi...
CTA4 is compatible with a number of PSD Editors but it is very important that the editor has full support for PSD files including Groups. Many editors can open PSD files but lack the full support needed.
I'm assuming you have already tried using Pixelmator Pro with Cartoon Animator without success. Is that the case?
A the present time the compatible PSD software for CTA4 is Photoshop, Affinity Photo/Designer, Krita, Photopea, Xara, Clip Studio Paint.
However, I will pass on your request. Hopefully the CTA team can do some testing to see if the existing problems can be overcome.
