SP 2013 guidance request: lookup results to be available as document properties

Question

I wish to request some guidance on the best path forward. I have used the Lookup column type for displaying linked information. The 'additional fields' appear as expected. Is there a way to have these 'additional fields' appear as 'site columns' ? I would like use the information contained within the 'additional fields' to be available as 'document properties' so I can dynamically update the working word doc. Sort of a double lookup - user selects cell from list, and based on that selection other 'site columns' get populated. I see there is another request like this one: [question]: Quick parts document properties from lookup columns?

Kind regards,

This proved to be a dead end. Needed to create columns to hold the necessary content. The library where the document is located, needs a workflow to update the columns of interest with the information from the source list.
