Right now one of our custom modules uses a customer's first name as its name. 

This makes it difficult to navigate between customers, due to different customers having the same first name very often.

One thing we could do is simply combine both the first name and last name fields into one, and having this full name field be the name of this module's references. 

However, having the designated first name is very helpful when we address the customer through things like Email and SMS. 

Is there an easy solution for this? I.e. some way of setting the patient reference be a combination of other fields?
