A method for a display-based terminal to dynamically group communication units in a dispatch communication system, the method comprising the steps of:displaying a map to a user of the display-based terminal indicating locations of a plurality of communication units; receiving an indication of at least one geographic area on the map to produce at least one indicated geographic area; receiving, from the user, an identification of at least one talkgroup; determining that a communication unit of the plurality of communication units is in the at least one geographic area; and automatically grouping the communication unit into the at least one talkgroup based on the communication unit being located within the at least one geographic area; and determining that the communication unit has exited the at least one geographic area; and automatically removing the communication unit from the at least one talkgroup such that the communication unit rejoins a talkgroup that included the communication unit prior to the communication unit being automatically grouped into the at least one talkgroup.
