TimoVeld on "[Plugin: WooCommerce - excelling eCommerce] How to make each product unique"

Is there a way to make each product unique?

For example, if somebody orders "product A", returns to the shop and orders "product A" again, I want there to be 2 seperate "product A's" in the cart, in stead of raising the quantity to 2.

Is this possible?
