Duplicate "On Sale" in woocommerce

Hi There,
On woocommerce there’s a field named “sale price”, if we fill that field with a price value, there will be showing a word “Sale!” on pict. I’d like to ask you how to duplicate that “On Sale” on woocommerce, i might change the name to be “Ready!” when i active it. So, i have two category “On Sale” and “On Ready”. Anyone of you knows how to make it?

Thank you for your assist!

Best Regards
