mutiple side bars?

Does anyone know if there is the ability to have mutiple side bars in Word press? basically, I am using the widget feature and Id like to separate the widget in there own little div or area.. I dont see in the side bar where I can find that code to separate them with divs BUT I did see under widgets in the WP admin that there is a drop down menu where you can possibly choose different side bars to assign the widgets too.. Im thinking I can control/separate/and style them that way.

Any ideas?
