Option to select a field for display name in a hippo:mirror compound

As an editor I would like to choose the field to use as a display name when linking to another document.

When using a mirror compound the name of the linked document is displayed. However, the name of the document isn't always the most relevant or the most specific information. This can lead to linking to different documents with the same name (but different folders). It would be nice if we could configure a field to use as a display name, either instead of or additional to the name of the document. This would be configured on the document type.

Default would still be to use the document name if the field selected is missing or empty.
