Using a SetUp table in FitNesse to define variables

I am using the tool FitNesse to do testing. I currently have a script on my test pages that executes a SQL query based on variables that I define on each test page. However, I would like to have one page where I can go and change all these variables at once. I was wondering if there is a way to use a SetUp page to define values to be used on my test pages.

For example, on my SetUp page I have a table with two columns a state and a date. I want to be able to define all of the different dates on the SetUp page and then use the date I need on the test page.

Is there a way to do this?
