document library – Change Default Column Values using Nintex workflow in SharePoint 2013

Quick summary of my setup:

I have a list that uses a Nintex workflow to create a folder in a separate document library every time a new item in that list is created. The folder name will be the list ID.

Issue:

However now I am trying to create a default value in one of the columns in the document library. I have been doing it manually in the “Column Default Values Settings” in the library settings.

I would like to create a workflow that automatically does this. Let me know if there are any questions. Thanks in advance for all the help.
