This would be more useful for groups that are in gang wars, since it may be that the enemy is attacking different places and more than one /mgd cannot be used, for that this would be useful, also for the CnR, like cops if several criminals are robbing several stores, the official group leaders would mark those places and so the members go one by one, the same as a criminal, an example that a CE/AR is happening at the same time, but only one can be marked, This would be that both could be marked and so each criminal can go to whichever one they like. Here I have given several examples of how this would be useful, but there are more options, but that will depend on the people and the use they give it. In short, a useful feature.
