How can I change toolbox generated filenames to spanish?

Hello,

I have Solidworks 2011 and I use the Toolbox mostly to insert screws and bearings. My Solidworks is in spanish, the Toolbox is in spanish, the names of the parts before I choose them are also shown in spanish, but after I insert them to an assembly, the part name changes to english. For example: Avellanado cabeza hueca hexagonal --> Socket countersunk head screw. I don't have any problem with the language, but when I take my drawings to the workshop I often have to rename the file or modify the description to spanish.

Does anyone know how to change this?

Thanks for your help!
