Change layer names according to description label

[Anonymous]

Hi to all, I'm new to Civil 3D and I have this annoying issue:

-What I have:
A map downloaded from Informative Territorial System with 5 numeric layers (31110000, ...) and a huge amount of different labels that specifies the description of each entity (civil building, field, chapel etc.)

-What I'd like to do:
Export this map as DWG (for Autocad) using the description field into the table as layer name. I'm not interested at the original layer's name.

Please help me, I can't find a way out.

Thanks a lot,
Regards.
