Importing Fbx/Obj Model with its properties from Revit to Unity


I am have imported a fbx/obj model from Autodesk Revit 2024 to Unity Editor (2022.3.9f1).
I have added ID as property to the fbx/obj model’s each individual object in revit.
Now the issue is that, when I import the file to unity, only the model is imported, no other information is imported. Is there a way to receive this data into unity as this id is required to understand every part of the model.
