I don't want to link some of my products to multiple categories because the subcategory folders would be exact duplicates. Instead, I want to be able to click on a subcategory that will automatically take me to another subcategory in a separate main category. For example:

Main1 - > Subcategory1

Main2 - > Subcategory2 - > Subcategory3

I want to be able to click on Subcategory1 and have it take me to Subcategory2 (display Subcategory3). Aside from actually creating an EZ Page to do this, is there a simple, dynamic way?
