Is it possible to create a single report that will be ran by multiple clients, each with their own data source / data set? Basically, I want to have the exact same report for many different clients, but don't want to duplicate my RDL files for each of them. If I have to make a change to the report, I would rather not have to edit each client's report individually. If I make a change to my RDL files, I would like it to update for all clients. I have googled this a couple times and found stuff such as "yes you need to use data source substitution", but no recommendations on how that is actually done.
