Changing the title of a form

We use Entity records to model 3 types of entities;
[LIST]
[*]Regular old customer
[*]Patient
[*]Doctor[/LIST]I'm trying to find a way to change the title of my forms to display a custom string that will make more sense to the user.  In other words, they can't tell they are looking at a regular customer or a doctor from a quick glance.

I looked at the page source and unfortunately the title text isn't wrapped in a <span> with an ID, so javascript hacking won't be easy.  It IS nested in a <td> that uses a specific class, so I suppose I could loop through the <td> checking class and then set the value.
