I've noticed that I generally go with one of a couple of troop compositions: Brutes and Gunners or Brutes and Thieves, for example. I'll have x number of brutes and y number of gunners over and over and over. It's be great if I could define "Squad A" as 4 brutes and 19 gunners and "Squad B" as 2 brutes and 27 Thieves. It's primarily useful for when you come back from exploration missions and need to round out your troops after a couple of each type get killed or in the event that I'm doing battle after battle every 30 minutes and keep using my same troops over and over to attack. If anything, it keeps me from just having to hold down the button on the last troop until the "Tavern Full" indicator blinks over and over.
