There are additional settings you, the administrator, can configure for dispatchers to temporarily add agents. You can enable more fields for dispatchers to search on.

By default dispatchers can add any agent to Dispatcher Workspace who is part of the assignment groups or territories they manage. You can enable dispatchers to add any agent to Dispatcher Workspace, even those outside of the assignment groups or territories the dispatcher manages. Note that dispatchers can only search for the agent; they cannot assign tasks to agents unless the dispatcher manages the assignment group or territory that the agent is part of.

Dispatchers can search for agents by their name, email address, or employee number. Administrators can allow dispatchers to search for any filed that is available on the system user table.
