place to store luggage in pisa train station?

Hi again -
We are planning a stopover in Pisa just for the day and would love to store our luggage at the train station if possible. When we were in Italy before some stations had luggage storage and others didn't. Do any of you know if the Pisa train station has a place to store luggage? It's for 8 people, so we really don't want to lug it with us during the day in Pisa.
Thanks for any tips!
