Move item on selection?

Well it's slightly hard to explain but I can't figure out how to do it and I want to if it is even possible.

I'ma making a capture the flag game and what I'm trying to do is make it so when a opposing player drops their flag a person on their team can walk up and select the flag and have it return to the base.

I know u can do this by when they pick up the flag and then have a trigger remove it from their inventory and then place it at the base, but what if their inventory is full? Also I don't want to do it that way because I'm not shure if that would mean I would have to redo my variable that the flag is set for, as that would create lag, a longer loading time, and take more triggers..so yea, any help is appreciated.

Thanks,

well how about making 2 versions of the flag: one that activates itself when you pick it up (tome-like) and one normal that stays in your inventory? then you make a trigger that adds the real flag when you use the fake one if you are from the opposite team or creates a new flag on its original place if you are the team that's supposed to guard it. also a trigger that would turn the normal flag to the fake one when you drop it/kill the one that has it.

TIMTOWTDI, but
On smart order with flag as target widget, if unit is on the right team, move item back to base and pause stop unpause unit

SFlip- I guess that would work but like I said I don't wanna have to reset all the variables for the flag witch are required to score and plus that would take a couple of triggers just to accomplish.

PipeDream- Um, you lost me...could you please re-phrase that in a way I can actually understand what you mean.
