Hey Pedro, thanks for the question! In the end this would come down how the cabinet in this case is modeled. The short answer to what you are asking is no, but there are workarounds. The best of these is to manipulate the model according to the materials you want to apply. For example, if you want the side of a cabinet to be a different material than the front, the side of the cabinet would have to be a "separate" model. By this I mean as a Revit family, the side panel would be a separate shared family nested into the overall cabinet model (if done correctly, the model in TM would show as a separate element for the side panel, therefore, the side being its own element). Another and simpler option would be to paint the side of the cabinet in the family and apply a separate material to the side in Revit. Of course make sure your import setting in TM are set to "keep hierarchy". Either of these would work and allow you to select the element (if the side is its own element) or apply the material to the object (that being the painted side face) based on your material application setting (see image). Hopefully this makes sense and helps!
