Model List - Controlling model name

[Homer S]

Is the unmodified unit name the only choice for model list? I'm using a dual unit name listing that is selectable based on options, like this:

Hive Tyrant / The Swarmlord (in model selection panel)

Hive Tyrant (unmodified, works in army list and most output)
The Swarmlord (option modified, works in army list and most output)

In either case , the model list name outputs as:

Hive Tyrant / The Swarmlord

Is there a tag or some other way to output the dynamic unit name in the model list?
