Is it possible to change document unit system for Toolbox components?

Hi all, thanks for taking the time to help.


I am trying to configure my Toolbox to only show the components I am likely to use. I am also trying to add a few custom properties to the Toolbox components.


I have successfully added the custom property Mass to Toolbox components, and it is related to their material (set to Plain Carbon Steel). The problem I'm having is that the document unit system (Tools > Options > Document Properties > Units) for all Toolbox components is set to Custom, with the unit for Mass set to grams. All components I create in SolidWorks use kilograms.


Is it possible to globally - and retrospectively - modify the document unit system for Toolbox components so that they use kilograms instead of grams?


Kind regards,


Chris
