Changing Global Variables Without Editing Part

Hi All,

Is there any way to edit the global variables of a part without first editing the part then opening the Equation Editor? I know that I could reference them into the assembly but this is no good for this particular part as it is used in many different assemblies across different jobs.

What I was hoping was to simply be able to click on the variable, as shown in this pic... ("Thickness"=2mm : "WIDTH"=205mm : WIDTH/2=101mm)

and edit them directly there from any level, assembly, part, etc. but no dice unfortunately.
