Every time I register a new product, I do this

Do I have to make revisions (delete and rewrite) during the review process after submitting everything? It's such a hassle. Is there no way to register all the products at once?

They keep telling me to delete and rewrite it every day, which is a bit of a hassle.

In particular, there aren't many colors for Yuki Color Gel, and registering them one by one means doing double the work.
