Shared Parameter vs Project | Revit

[@uzayozbey]

Hello, I have a question. When I want to make a curtain wall from floor to floor in Revit, when I set the 'top constraint' value to the upper floor, the windows go inside of the floor slab, so the top offset; I set it to be 'minus the slab thickness'. However, when I want to change the floor thickness afterwards, I have to manually change the top offset of all the windows so that they do not go into the floor again or remain exposed. Should I define a parameter or anything else, what would you recommend? Thank you.
