Nope, your options are parameter based filtering or possibly actions (don't think this works with multiple sources) or joining the table at the db level rather than using blending.
There is an idea in the forum to ask Tableau to do this: http://community.tableau.com/ideas/1126
From the thread linked from there, it seems you can use actions as well. My first route would be to see if you can use joins or custom SQL to get that data in one table.
thanks for quick reply , I have blended data so now I have one datasource.
Could you pleasee explain how do we use quick filter of 1 datasource to filter across multiple datasources using 'ACTION FILTER' option in Dashboard -> Actions
