Pass the XML path to the swf

I understand how to create and pass XML data to my dashboard. Is it possible to pass the XML path so that I can control which XML data set is read?

For example, I could have an individual edit an existing dashboard with local XML test data (file:
C:/temp/test.xml)

which I can provide. When finished, they could load the dashboard to the web where a different XML path (pointing to production data) is used.

Can this be done?

Many thanks,

Jim
