In the Plus version, you can assign the quote status to one or more product categories in the premium version. You would create the categories in WooCommerce.

Please note: to check the check this to apply the categories before saving every time you want to apply this setting. If you want to remove all categories, then delete all the categories from the select box, check the “apply the categories before saving” checkbox and save setting.
