Product in Multiple Categories

Hello,
I see that I can add a product in a main category and then to many others.
SEO-wise, when I see a product from another category than its main one, it should have a noindex nofollow tag to avoid duplicate content. Is this feature available? And if not, could you implement it?

Hello George,

This is not available. I thought about that but when a product is assigned to the main category, then link to that product should be depend on the main category so we will not have the duplicate content.

Sincerely, Giang
