Sales/Purchases: Set a minimum level items for items to sell/purchase

Hi ,

Is it possible to have a switchable pop-up warning that notifies a user that:

1. A Minimum Quantity or Bulk Quantity applies to the sale of a specific Item (when Invoicing). This would be particularly useful on low cost or low margin Items, or sales at wholesale prices.
2. A Minimum or Bulk Purchase Quantity applies to that particular item (when creating a purchase order). This could be used as a warning to ensure the purchace of just one Item justifies the cost of freighting the Item in, and/or to remind the Orderer that if more than "x" number will get better discount or better freight rates.

Either of these would also be useful if offering a Bulk Sale Discount Promotion (could be switched "On" for the duration of the Promo, and turned "Off" afterwards)
