I found the same issue as you.
My solution was to add a FreeCAD Spreadsheet object ....from the spreadsheet workbench.
Assign my own variables.....remember to right-click on the value and assign the Alias the same as your label....that keeps things simple.
Then you can change the value at one location and it updates immediately in the Path Gui.
Maybe we should be building on the basic building blocks within FreeCAD ...so we don't re-invent the wheel.
Use a standard spreadsheet object.
Have the first 12 items labelled for system use only.
Provide a 'Reset to Default' for when silly users meddle with the variables and hose it.
And then let users add and modify the spreadsheet like any other FreeCAD object.
