Easily add a choice to a drop-down list especially when this needs to be done alphabetically.

Need: Have a dropdown field that makes use of a single list of choices to maintain and no longer have to complete form by form.

The forms will make reference to this single list to be updated.

Objective: administrative gain in terms of maintenance / ease of updating

Example, in our case, every time we add a site we must review and update 80 forms.

I'm now working on a drop-down and it's extremely tedious. The Dependent Field form is much easier - it would be nice to be able to just use that exact UI for generating lists as well.
