I propose to support the layer descriptions that are frequently used in DWG or DGN files. Many CAD resources that we still need to use come with this format:
"Layer Name","Layer Description"
"01_8716843223","Human readable description that states 01_8716843223 is actually to contain cut walls."
"01_8716843224","The Layer 01_8716843224 will contain annotations to the previous layer."
Inside Revit the imported categories tab only shows "01_8716843223" and "01_8716843224" which is not sufficient in this situation.
