[Feature Request] Add display name field separate from agent identifier

Question

**Bug Description**
I would like a feature to have a pure display name field for the agents. That way I can publicly post an agent with a detailed name but have it named something else in my terminal. Changing the name field or file causes changes in other locations. A simple display name would be amazing.

**Environment Info**
- Platform: darwin
- Terminal: Apple_Terminal
- Version: 2.1.185
- Feedback ID: df8f49f5-7b47-413d-a922-edd63f008dee
