Version: Zen Cart 1.3.9h

I have been searching but haven't found an answer for this. (for 15 months)

In this store, the owner would like the ability to add to cart if quantity is 0. This is how it is currently set up.

However, here's the problem: He also sells 1 of a kind items - so those can't be sold if the quantity is 0

Is there a way to select products to allow backorder/preorder and which don't?

A way to allow the sale of SELECT items when the inventory falls below zero.

Sold Out items say sold out. Pre-order items can still be sold with a stack value of <0

When going to admin->configuration->stock, there simply is one option missing "allow pre-orders on select items". This would then need to be a selectable field on the product (admin) page itself.

I have asked this before and am still looking for a way to do this.

Will this be something that will be available in v1.5x?
