Automating tolerances in Solidworks 2012?

Hi guys. Doing Solidworks project for college.

Basically we need to define tolerances in our drawings and don't have time to do it one by one (a lot of drawings, and we're out of time). We already made all the drawings except adding tolerances to our dimensions (we even decided manufacturing methods). Is there an automated function that can add tolerances to all our dimensions in the drawing based on simple accepted standards?

Thank you
