Help with Content Manager

Firstly, thank you very much for replying, I really appreciate that. I understand exactly what you mean. Of course the foreign key is to the primary key of the child table. But they could certainly write code to query the table, then sort the returned collection and populate the dropdown with the stipulated sort. BTW, they already sort this by descending Created Date, as opposed to the ID, so they certainly could have, if they had wanted to, provide the facility to state the field on which to order it. I guess the bottom line is, they haven’t done that, and I suspect they won’t. But thanks for your reply J.D., at least it confirms it can’t be done with the interface provided, and I really appreciate you replying.
