We have a long list of 'Sites' in our Org that updates often. Separately, we employ several custom fields to list these Sites for use in dropdowns. It would be helpful if we could link a custom field to the Sites list, or any two fields for that matter, and have it automatically pull the up-to-date list from the other field. IE, a "Truck Relocation Request" form may require two custom fields for "Origin Site," and "Destination Site." Currently these two custom fields need to be updated any time the primary Sites list changes. We have 5+ 'Site' fields for catalog forms, increasing the chances one gets overlooked in an update.
