This did not seem to be in the can not do list. It is not to target, change, modify anything. It is just a simple way to let the raid leader have the marks pre configured to where they want to place them. This is more to save time as they could do this one at a time but it would be nice to just be at the boss and hit a button and the marks are set where the raid leader wants them and can spend more time on other segments of the fight.
boss1 = raid leader uses 2 markers - hits the key and they are set with the colors wanted
boss2 = raid leader uses no markers
boss7= raid leader uses 6 markers - hits key and they are set with the colors wanted
have this set only for markers that can be placed on the ground as they are used more for reference to mechanics that are to be done and have no other value.
might consider that the raid leader first set the markers where he wants and then can save the positions to a file and name it so when it is there again he can just click the file and sets the markers to the same color and location.
