Is it possible to use the name of a material category (not just material) as an attribute, so that I can show it on my drawings? 

I have a custom material library, but if it were the standard Solidworks material library, then what I need to show on my drawing is for instance "Steel" instead of "1023 carbon steel sheet", and "Aluminium Alloys" instead of "1060 Alloy"

Reason is that we do not want to specify the material towards our customers, we only wanne give them the category. But i still need the different materials, to get the right density/weight on the drawing. 

Eg. 

PE foam

            PE foam type 1 20 kg/m3

            PE foam type 2 30 kg/m3

            PE foam type 3 40 kg/m3

Tekst neded on the drawing is "PE foam"
