[MicroStation 10.14 C#] Is there a way to change the Display Label of an ItemType shown in Explorer

In a C# MicroStation addin I'm creating itemtypes programmatically and applying them to elements. My itemtype is "BoreHole", when I view the results in Explorer I see BoreHole with a list of all the BoreHole itemtype instances I've placed. Is there a way to change what shows up in the list instead of the itemtype name?

Below is what I see from my application:

I would like to create a list that appears like what the Bentley Gint geotech package create (where you are shown the Borehole number instead of just the generic itemtype name. (see below image)

Any ideas? I don't see anything like a label or display name that I can find.
