i was wondering if there was a faster way to add all the Child elements to a menu system. Doing them one at a time page by page takes forever when you are first doing your organization.
 
I am a sports fan item store, so i have 5 different sports with all the different teams available. So you hover over NFL you get all the NFL teams. Doing these one by one just takes forever.

If you are referring to adding items to a secondary category (not the primary), if you go to the "products" link for the category you are wanting to add to (next to Custom Layout link - where you view the categories down the right side), this lets you add products from other primary categories to the secondary category with the click of a button. (I'm using 4.0.)
 
I hope this helps!
