AI content creation with customized design template

I know I change fonts and colors from “Theme.” My question is whether we can save the same theme as a template and apply it to AI-generated content without having to redo the settings each time. This might be a new feature request, but as it stands now, after creating content with AI, I have to change the fonts and colors to match a unified design, which takes a lot of effort. (In other projects, I create content by copying items saved as design templates, but since I can’t select the “Create new with AI” menu from already created content, this is very inconvenient.)
