A display-based terminal (101) employs a method and apparatus for dynamically grouping (719, 723, 819, 823) communication units in a communication system. The terminal displays a map (703, 803) to the terminal user that indicates locations of communication units in at least a portion of the communication system. The terminal receives (705, 805) an indication of a geographic area on the map. After the area has been indicated and the talkgroup identified, the terminal automatically groups (719, 723, 819, 823) communication units that are in or have entered the selected area into the identified talkgroup. If a regrouped unit exits the selected area, the terminal automatically removes the exiting unit from the talkgroup. The terminal user may further input criteria to limit which units entering and leaving the indicated area are actually grouped or ungrouped.
