Creating a unit in a transport.

Is there a way to create a unit directly in a transport or other such cargo capable unit, rather than having to issue an Board order to the unit after creating it? If not, what would be the most effecient way to achieve this effect? I don't want the units to be visible for the split second between when the are created and board.

Also, can you queue orders via triggers? Like ordering a unit to unload all at a point and then move to another point.

For queuing orders you can just use a wait for condition, the condition being that the current order of the unit is not the order it used to be. If you need to do this for multiple units just use some of those funky Table things. And if you need reference for checking the orders take a look at one of Vex's charge spells or Blade.dks charge spell pack(Airy Charge is the one to see)

I'm pretty sure it's impossible to create a unit inside another one, but you could always create a different unit way far away, load all the units inside it that you need, and then replace the units.

OK, thanks for your suggestions guys.
