Can anyone tell me if it is possible to have multiple flags on a map, which, when any one of them is captured, wins the game?

I want to create a scenario where the Allies have to capture just one of four flags on the map to win the game.

A random guess would be to try and have each flag in its own flag system. Seen as you can't trigger the end of a round on a single flag cap (I looked at ouputing "setendround" on the master entity to no avail), it would seem the only way to do it is to trick the code into thinking there are no other flags.

try this: have 4 dod_capture_area's all linked to one dod_control_point.

Irate's idea works fine, I just need to create a way of identifying the areas as objectives.
