It's cumbersome to need a unique custom field for the same data across different item types. It would be more efficient to be able to use a single custom field in multiple item types.
For a use case, we have a droplist that contains a list of clients. That list is rather long and we have the same client list for ideas, features and releases. When a new client is added, we have to add the client to each droplist. Currently, we have a note that contains the list, we add the new client, then edit each droplist. This manual effort is prone to error.
