How to reduce allowable number of player units in battle?

[Ansehelm]

Heyo homies,

I'm looking to create a random battle (a specific floor of the DD) that only allows the player to enter one unit into battle, as part of a duel scenario.  I've run across a random battle editor here, but my cursory review of it at least did not make this capability obvious. Am I missing something there, or is there another method to unlock this madness?

Its in the attack.out gui squad editor. Lets you choose how many characters can be used in formation.
