I really don't know where it is shown, but there is an option while uploading and configuring the asset.
The process is very simple, though ^_^ Something like this:
Theme Selection > Brainstorming > Definition of 20-30 Samples > Draw Sketches > Prompting (Personal Library) > Sketches to raw Product (AI) > Refinement > Standard Check > Pack
Simple pipeline, results getting better and better ^_^
