Make my Single-Target Buff Spell affect up to 2 units at a time.

[asdfdude]

Hello. My problem seems like it should be very easy to fix but I'm new on WE and suck with it. I basically made this quick Buffing spell that adds bonus stats to a targeted unit. It works fine on its own. But I was thinking about changing it so the spell is able to buff up to 2 units at a time (currently have the spell/buff duration at 20 sec and the CD at 10 sec). But since recasting the spell a 2nd time on a different unit also changes the targeted Unit Variable, it leads to the previous target keeping its bonuses forever (and so on if I keep targeting a different unit). If someone can whip up a quick fix for me, I'd appreciate it a lot!

Simplest way is adding them to a unit group and periodically check every unit in the group. When the unit in the group doesnt have the buff remove the unit from the group. When there are 0 units in the group turn off the trigger.
