[oXygen-sdk] Show EditorVariablesResolver custom variables in 'Custom Editor Variables' in 'Preferences'?

I am using an EditorVariablesResolver to add two custom variables. That works, thank you. However, I was surprised, and then another developer was surprised, that the added custom variables do not show in the 'Custom Editor Variables' list in the 'Preferences' dialog box. Is it possible to show the programmatically-added custom variables and their current values in the 'Custom Editor Variables' list even though the variables can't be edited from the 'Preferences' dialog box?
