How to control field label for MorphTo?

[tractorcow]

If I have a model with separate morph-to fields (e.g. creator, editor, and so on) the field labels seem to end up being inherited from the selected type. Instead I really need those labels to reflect the name of the relations as that is important context.

I.e.

Creator: <link to creator>
Editor: <link to editor>

not:

Admin: <link to creator>
Admin: <link to editor>
