Is there a way to have both of these functions simultaneously?

Here is what I'm trying to do.

Let's say, theoretically, there's a tank in my group named Cassim. And I always want to track the number amount of Divine Aegis on him. To do this, I would have to click "Use Full Scan" so I can set the aura to "size" instead of stacks. But if I click this, it disables the option of using a Specific Unit Name. Is there a way to do both?

Thanks a million in advance!
