Creating reusable sets or groups of data in TBC is really easy, and enables you to use the same information for multiple tasks - for example you can create a selection set from a set of points, use that selection set to create a Point Label Table, to Label the Points and then Export the Points to a field crew for control or stakeout purposes.
The key is to create the Selection Set first if you intend to utilize that group of data for multiple tasks.
You can have as many selection sets in a project as you need, there are no limits.
