Product SKU - unique checker

[marvays]

Hi. I have question. need any solution for unique product SKU. Is any plugin, when can check all product sku in Vm and send message if any sku is duplicity? Either when saving the product, or independently from the administration button?
Thx for idea.

Atm not, but you could hack the core. it is just one line to add to the table. We could add it as hidden config, when you buy a membership
