Comment 8 for bug 1493071

Stefan , I think that better practice is having a single "C" and a "Cpol" in device.lib, where Value is simply "C".
When you place the component, you may edit its properties with "E" key.
Set Value from "C" to "1nF", set Footprint by "Assign footprint", and "Add field" only if needed (e.g. "Voltage"= "50V").
Or simply set Value to all important things like "1n/50V/X7R/SMD1206".

No reason to make separate components for each capacitors (e.g. 1uF_100V_2012_5%).
