Ceiling vs Floor

Would it be possible to differentiate the specific location of vents? I have 5 vents on the second floor and they are all on the ceiling. I have five more on the ground floor which are all on the floor. It would be very useful to differentiate the floor the vents are on and whether they are on the floor or ceiling. For example my master bedroom is on the second floor with the vent on the ceiling. The flair app leaves the vent open if the temperature is below desired , but if heat is not turned on (the rest of the house and downstairs is at a normal temp) then that is just heat escaping making the room colder.
