Hi, you are correct, parameter selection is not part of the system default IC matching report. The way to go about it is - as you did - to use (e.g.) a Method Query Data Adapter and set up the IC matching report the way the customer requires it.
You can make this very flexible and nice using e.g. grid views and link those together. I personally prefer those over PDF reports, but it is all a matter of what the customer prefers.
As for your exact test case, if you think this would be a great enhancement of the product, please post this to IdeaStream.
