Yep, that would be the best way. I see three possible mechanisms:

An action responding to "..." to launch some UI.
A way to list auto-complete suggestions for a partially typed value.
A way to validate a typed entry as "invalid, good, or unknown", (for
example).

For any given attribute name, there might be any number of these.
