I am hoping someone can help me with creating an infrastructure view (map);

We use a mobile work scheme so very few people have fixed desks, as a result the users all move around using their laptops on hot-desks, I've mapped each of the switch ports connected to the desks and given them a description on the switch which i can see fine in Switch port mapper as the alias. 

I am trying to create a map using the office floor plan showing the interface on the desk in question, i know i can add devices into the map view but i am trying to add the switch interface with no luck so far.

Any help would be greatly appreciated.

Many thanks
