Automatically display the number of a custom variable when it's enabled in SiteCatalyst, in the menu

A best practice that I use, to make it easier for analysts to find reports related to custom variables (traffic \ conversion \ events \ hierarchies) is to put the # of the variable in front of the friendly name of the variable in the reporting interface. For example, if I have a traffic variable named "Sub Navigation" I'll set it up in the admin panel like this (theoretically as s.prop2 \ traffic 2): "2. Sub Navigation".

If I enable a custom variable in the admin panel with a friendly name, it would be great to have the # of the custom variable automatically appear in front of the friendly name of the active custom variable, saving me a few characters (or having to remember to do this myself) in the friendly name field for custom variables.
