Check if an Enemy in Troop Died

Just curious to know if there is a script call that can run to check if an enemy in a troop has died. I am using Yanfly's Row formation:

I am doing some Lunatic mode row modification and I am trying to have an enemy switch rows when one of his "companions" dies. In other words. I kill the enemy in the first row and the enemy in the second row moves up one and the enemy in the last row moves up one. Then I kill the enemy in the first row and the enemy who was now in the second row moves up to the first row. I know there are plugin commands to switch rows during battle and that is fine. But I need the condition check to see if a member of the troop has died.

Any suggestions are appreciated.

Try this on conditional Branch in the events troops box .
To check if a troop member has died.
-The list of individual enemies (in a troop) is generated based on your customized troop configuration
-just choose the enemy individually and you're done

Example:
You enter a battle with a troop consisting of 5 rats, then the automatically generated list by the engine will be like this:
number 1: rat => IF rat [1] died THEN do stuff...
number 2: rat => IF rat [2] died THEN do stuff...
number 3: rat => IF rat [3] died THEN do stuff...
number 4: rat => IF rat [4] died THEN do stuff...
number 5: rat => IF rat [5] died THEN do stuff...

Got it alright. Thanks for the help.
