Conquest landbase and TG/target issue

[mingohh]

1) Is it possible in a scenario to let a Axis landbase switch side to Allied at a given time. As with TG you can let a tg leave map and created a new to come later.

2) Can i in the warrom set a TG to leve and then let it return later without the sunk ships.

3) Can i have transport carrying squadron of plane as supply, and set it to deliver it to a airbase when/ or if it reaches habour.

4) if i created landtroops/guns/tanks as a aircraft and only to be use as a target,and set it flying to speed 0, and range 0 will this interupt with the game handling aircraft and their roll in the game

Just asking because im trying to work out a campaign over a couble of month.
