Tagging levels

hi,
I am using revit 09, i need to tag my floor levels (both Structural slab lvl and finished floor lvl) and i need to tag my false ceiling lvl in floor plan. I tried with spot elevation for floor slab lvl i am able to get FFl but i don’t know how to add prefix (FFL) to it and i also don’t know how to bring SSL (Structural slab Lvl as i said before!! And i need box around my tags (please refer attachment). For false ceiling i am drawing a line by underlying false ceiling plan and locking with my ceiling but don’t know how to bring the level for false ceiling in floor plan. For Time being i am using everything as text............please help me to solve this issue.

You are not going to get them into one tag that provides both slab levels. You may be able to create a custom spot elevation that provides a box, I have not tried that before. In order to get both levels, you'd have to model both floors/levels. I do not believe you can add shared parameters to this tag, that would "calculate" the structural slab from the finished level, or visa-versa.

You can do the box by editing the label used, but certainly not get both heights at once.

I am alos battling to get SSL when the floor is modeled with finish. A formula referencing FFL seems impossible and there is no other way I can find to reference top of structure allthough the floor itself makes the destinction.
