Organized Dynamic Access Driver Selections

As a model builder, dynamic access drivers can be hard to find when implementing this feature. Anything formatted as a boolean will appear as a possible driver and the resulting list becomes tedious to search through in big models. My idea is to show potential drivers based on the current module on the top of the drop-down list. This will enable model builders to quickly and easily seek out dynamic access drivers within the current module first without having to scroll through ones from different modules. It will also help eliminate some confusion if drivers have similar names across several modules.
