[Request or question] Event on X, Y. And event buggy

I have been making Creats events that you can push around the map. But there are some problems..
1. When I use an event on a tile with the Option: Direct fix and Though so the creat can be pushed over it. But then the event that should be below show on top of the creat

2. Useing Variables and Conditional Branchs can chose the Players X, Y Location. But not for events.
So I can't make a switch that the creat has to be on the X, Y Location to actived a switch... 

Either I don't know how to do this. or I need a script.
If you don't understand what I mean. I'll try to make a Demo about it.

This should be what you're looking for, I expect.
