You can't create an object directly in another layout.
What you can do is create conditions in layout A which are checked in layout B and in the eventsheet for layout B create the object if those conditions are met.
in layout B you have this event:
System compare global variable VisitedA = 1
System trigger once
And in layout A you have this event:
On start of layout
- set global variable VisitedA: 1
