Crystal Reports - Suppress Non-Consecutive Duplicates in Group

I'm working on building a report that pulls name data based on a specific report identification number. I have the information grouped by the report number and want to display names related to the report. The problem is that each report number can/often does have subsequent reports written that are attached to the same number which include the same names, thus giving me duplicate names in the group, but not listed consecutively. The report looks like this currently:

Report #                Name
170001                   Smith, Bob
                                Doe, John
                                Doe, Jane
                                Smith, Bob
                                Doe, John
                                Doe, Jane
170002                   Jones, Mike
170003                   White, James
                                White, Jack
                                White, James

I want to suppress all instances where there are duplicate names under the same report number.

Thanks in advance for any help!
