Questions about sub-missions

[28_Condor]

At last, I managed to do some submissions work but I have several questions:

1 - The main mission and sub​​-mission must have the same configuration? That is, if the sub-mission has different weather conditions or time they are loaded or conflicts happen?

2 - The submission can upload new boundaries on the map or new airfields? I tried a change of side (red for blue) in an airfield but it not totally worked. Who flew during the exchange could still see that as their airfield.

3 - The sub-mission briefings can be used? How?

4 - Which method can I use to load a new mission (or the same) from a trigger? That is, not a submission, but a new one, like a rotation map.

I appreciate any answer to these questions

Thanks
