Other clients who have wanted custom LEM reports have had Crystal developers on staff. This does not help regular users, as out of 100 clients only 2 have had Crystal developers. You can always hire a contractor to do it.
The closest solution (as others have said) is to apply a filter to the existing report. But that's just for starters, if you want to change the name the report - there is this a procedure we have to go through which involves copying the report to to a 2003 server. How to change name of custom report
I believe we still have to do this with LEM 6.2.1
