While nothing is built into Zen Cart for this at this time, you can use an export/import method for this ...
If you export the records for a Product that is already setup, say products_id = 17 ... export the records for products_id 17 from the products_discount_quantity and change the 17 to the next products_id number, example products_id 23, that you want to use ...
Then, edit the products table and set the values for:
products_discount_type
products_discount_type_from
that you see set for products_id 17 and change for your products_id 23 ...
This will let you build these faster ...
You could even write a mini piece of code to manage this for you ...
Have you got your coder's hat on?
