2012 routing library manager - coverings

Hello all,

Does anyone have any idea at all why the coverings colours that are set-up in the XML spreadsheets for cable covering data cant be changed? I have tried to add a simple brown wire for Live but seems that the only options are yellow and black. I typed "brown" under the colour column, and it seems to default to yellow or black.

It would make you hope that  SolidWorks Electrical is not based on routing, as i think its its performance is very poor. I have 2012 SP1.0. Do you know if this part of Swx has had any enhancements since 2012?

Thanks
