Is thre a way to do this, or do I have to use additional categories to include all child products into parent categories?

ie:

product is a boys hat

clothing -> boys -> hat

I want it to show under clothing as well as boys, so that they can use attribues as filters and/or/instead of category navigation. I dont want to force them to go to the lowest level category to find that item. Thanks!

Of course I found it 5 minutes later....I had to check yes to show subproducts...

Unfortunatley I cant do that too high up as I have 26,000+ skus under 'Projector Screens' and the pagination options on the top of thee page occupy most of the spce above the fold.... oh well
