Edit Data source in multiple reports SSRS

I'm using ssrs and I have a boatload of reports that I want to use a different datasource on.
Is there away to mass edit the datasource of multiple reports at once?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Please have a look if solution from link below applies to your case as well - it is about "changing" not "editing" indeed however I assume you want to do a mass change rather than edit - just make sure you save and keep safe a copy of the originals before making any (mass or not) change.

Or maybe this better for your needs?

There are also some power shell options that you could use to do a mass update.
