Displaying rows with a duplicate same-column value

Hey all,

Relatively new to PBID, and unfamiliar with backend DAX queries. I'm probably overlooking something, as it seems this should be simple.

I have a table structured as below:

Row     Owner          Oppty     UniqueID    etc.

1          Person A       MSFT      1

2          Person B       AAPL       2

3          Person C      GOOG      3

4          Person D      AMZN      1

etc.

All I want to do is display all rows with duplicate UniqueIDs, e.g. rows 1 and 4, and filter out everything else. As far as I can tell, there's no built-in "Show items when the value: is duplicate" filter (though it'd be nice if there was). All the solved questions I've found have dealt with either filtering out the duplicates, or highlighting duplicates between two different columns.

Should be simple. Thanks for the help.
