well, as an extension of Theonlystd's comment...
You can always hunt and peck to find units of interest in the battle screen. But if you could color-mark or flag any unit of interest... similar to the "blue vs. red" discussion ... it might cover HOFers or any unit the player particularly wants to pay attention to.

For example, I just finished off a mega-battle (2400+), and wanted to track a few SC's I created (sea kings and golems w/ boots of flying, wraith swords, wraith crowns, stone armor, bear claws, lucky talisman) and a few supermages scripted to cast battlefield-wide spells... and it was very difficult to keep finding them to monitor their progress!
