sheet metal thickness in drawings

Hi, In previous version of SW first sheet metal feature added a new linked value called "thickness" (in equation folder). So, now I can design multibody sheeet metal parts, but how can I link each "thickness" value as custom property for each sheet body - I would like to show these parameters in table in drawings. I don't understand, why this is not solved... I can link only firts one value, but what with next bodies? It is not implemented as thickess2, thickness3...I don't like this piece of multibody functionality in SW 2010SolidworksSheet Metal
