Using an Action to label a summary table with constituent data

Hello!

I have a bunch of tables with summary information presented in them, and I'd like to create an action that would allow a user to click on a data cell and display the names of all the data that makes up the total. There is a similar function in maps, where you can label the marks when selected, but I can't seem to figure that out.

I'll eventually have a bunch of tables in a dashboard, that I'd like to have this functionality for.

Any help would be most appreciated.

Thanks.
