Sorry, Travis, I just noticed that you never received an answer to this question.
Currently you cannot set the system to use the Calling Party Name associated with the user or queue. That is a feature which is being worked on, and I think will be another check box in the Trunk settings to decide whether or not to override the name based on whether the value already exists, same as you can for the number.
I don't have a time frame on release of that feature.
