As Matthew mentioned you don't have a huge amount of choices when it come to objects on storeys.
You may be able to do some scripting in GDL that wll give you more control.
But it is very easy to control objects by layer and layer combinations.
So instead of setting up different storeys for floor plan, site, plan, roof plan, etc., you could have them all on the same storey but controlled with layer combinations.
It may not suit your particular job/template setup now but it is certainly something to consider when setting up a new template.
I like to keep it simple and have a storey for each floor level and then use layer combinations for each plan view.
That gives me the best layer control for objects - especially stairs.
