Is there any bulk insert addon for quantity discounts?

[Jacksback2]

Does anyone know of any addon for uploading in bulk, quantity discounts?

Even perhaps manually allowing categories to be set up, and the discounts would apply to all items in that category. Different discounts for each category.

Have had several accounting packages for last 30years either allow bulk update or manually applying different discounts to each category, so am surprised that neither option to my knowledge is available in Zencart.

O.k. so no answers?

Seems thatSoftewareGuy has something called Table Discounts which may do the trick. If anyone has used, some feedback would be great.
