Is there a way to get a certain amount of minerals every time you kill a unit, without making a ton of

"When Current Player Kills 1 men"
"When Current Player Kills 2 men"
"When Current Player Kills 3 men"
etc... triggers?

My map will essentially have heroes killing computer units and getting 1 mineral for each kill (individual, so if you don't kill, you don't get money), however my dilemma is that I want this trigger to work infinitely.
I was thinking of using a death counter (computer has suffered X deaths), but I don't see how I can get that to work so that only the player who killed the unit gets minerals.

MAPLANTIS FTW!

Is it possible/probable that multiple units will be killed at once by a single player in your map?

K, Thank you. It's possible, but not going to happen often enough to make a huge difference.
