How to update a report object on multiple reports

Hi,I just had an interview, in which I was asked to update say the heading on say 30 reports at once; with put going into each of them. And naturally, each would be different from what they are now. I thought that I could make a table in SQL server with object name and a procedure that would look at what they are not and change them, but I would not know how to apply thing at once. and maybe I am thinking of this all wrong. So any ideas would be really appreciated, because so far I cannot find this on line.Thank you
