How to link/forward one category to another?

[idc1]

As long as the products within the categories are to be consistent, ie identical, try linking. Products can be linked, not categories, so once you have Category 1 and it's products set up, link those products to Category 2, 3, 4 and 5.

Thanks for the reply. I am familiar with your suggestion but that is what I am trying to avoid. Whether I add a product or delete a product, I would have to make sure to link or remove 5 times. Unlike if I could just link/forward the category I would only have to make the change 1 time.
