Editor: Remove unit when AP<100

[Erik2]

Hi

I have a few glider units in a custom , the gliders are removed by a round-2 event.
Problem is that the units have leftover APs on round-1, and can thus be used for two air-lifts. Removing them at the end of round-1 will not solve this.
Is there any way to remove the units immediately after their APs are less than 100?

Thanks
Erik
