Mission Planner: How to set a flight with a delayed start?

[MadTommy]

Hi, i'm new to the IL2 series, but i always like to make missions in the sims i fly, so i've been playing with the Mission Planner tool.

One thing i can't figure out is how to create a flight that does not start at the start of the mission. Say the mission starts at 12:00 and i want a flight of bombers to spawn at 12:30 for example. I can't see an option to do this, but i assume it must be possible.

Any help would be much appreciated. Thanks.
