Agent's profile

I find there are five attributes about tickets in agent's profile, can i add more, such as inbound or outbound call, brand etc. I was told that the Attributes that I see in the Agent's profile are native settings,  It is created by our Developers and changing it will affect all our customers as well. I think on this issue all customers will prefer to see more attributes, it will be more helpful, and no harm to all customers.
