Please help with my Platform Movement Object issue.

I have been working on a game for a while now using the platform movement object, but the game is up to 4 players at once one one screen. I have 4 platform objects and it automatically assigns 1 to the player number specific to it. Although I'm sure there are better ways to do this, custom movement would not only be harder but it would probably be harder on the game's performance. I was trying to use qualifiers to make 1 event relate to every platform movement object, but this does not seem to work. Duplicating the events 4 times worked alright but as the game develops, I have hundreds of events that could be removed if qualifiers worked for the platform movement object. I have tried re-arranging the order of the events but still, no dice. Is there something I am missing?
