How to put more than one attribute on a single line of text? (SW Electrical)

Hi,

When placing wires I'd like to automatically show their  color codes and cross-section seperated by a slash, according to DIN47100. 

Example: a blue wire with gauge section of .50 mm^2 would display a mark of "BU/0.5".

Ive tried editing the symbol attributes of the wire label in configurations tab. This clearly works for the attribute individually, but when trying to put them on one line "#WIRE_COLOR_CODE / #WIRE_SEC" only displays one attribute. Justifying the text is almost pointless because if the color codes are long enough they always overlap with the wire section 

I hope my question is clear. I am still learning my way around SWE, apologies if the solution seems obvious.
