Assign Context from the Story Bible

Can you add a drop down menu that allows the writer to assign different contexts from the Story Bible (SB) to a character, location etc.?

Allow it to cross reference existing data within the SB.

As an example: I would like to be able to create a home world for my character. I would like to be able to open a dropdown menu, label it homeworld, and have it search all locations listed in the SB. Or one for her cultural background… etc.
