BULK copy functionality using the "Duplicate Product" "Copy Method"

BULK copy functionality using the "Duplicate Product" "Copy Method"

I know how to copy a single product from one category to another using the "Duplicate Product" "Copy Method."
However, I do not know how to BULK copy all products in a category using the "Duplicate Product" "Copy Method."

The "Copy ALL Products in a Category as LINKED Products to another Category" in the "Global Category Link Changes and Master Category ID Reset" section of the "Products to Multiple Categories Link Manager" seems to provide the BULK copy functionality for the "Link product" "Copy Method" only.
However, what I need is this BULK copy functionality but for the "Duplicate Product" "Copy Method."

Does a BULK "Duplicate Product" functionality exist in Zen-Cart v1.5.0?

Thanks so very much!
