Show Cue System

When I set a loop in a cue, the standard level points are disabled and vice versa. Why?
I normally set loops on most of my cues and would be very happy if I could set standard level points on them instead of "change level" sub cues.

If you think about it logically, it will become clear to you that level points within a loop do not make sense because the player cannot know how many times he should take the level points into account.
