Suppose there are three categories of fields on your form, say Presales queries, General queries, technical queries. Now, if you want to assign these queries to different agents. You can easily do it in the following manner:
Technical queries to Agent 1.
Presales queries to Agent 2.
General queries to Agent 3.
That means, query handling process is becoming simpler and easier. And all the work is centralized at one place. When a new query of particular category comes, it will automatically transfer to the agent who is expert in handling that kind of query.
