Is there a way to extract data from JRS into a Report such that multi-enumerations are on a single row for the same artifact and not on separate lines (with each line for each different enumerated value)?

Hi Michael,
I don't know how you would do this without dropping into Advanced SQL. It would be tricky even then because you would have to concatenate all of the individual enum literals (which implies to have to know how many you have and how many are possible). Just thinking out loud -- I'm no SQL expert, but I spent about 15 minutes looking at it and nothing popped out at me.
