Customize the design of each category page of my store?

Is it possible to change the layout for store categories and subcategories?

This is my main store page which will have this this title and a blurb underneath. 

I want each category and subcategory to have its own unique blurb and layout. Is that possible? Right now it seems that whatever changes I make to the main store page also appear on the subsequent category pages of my the store. 

Do I have to just create many different stores? Or is there way to do it with code within one store?

Thanks!

Please see the following.

Hello! Thanks so much for your reply! I have installed all the parts, but it is not working. 

Only the default block is showing on category page.

Am I using the wrong category titles?

pass: 123

Thanks so much for your help!

Actually, I think I figured it out! I didn't realize it was case sensitive. Now everything is displaying. 

Thanks again!!!
