Customization of Toolbox - Screw Clearances - Adding a column other than Close, Normal or Loose

Hey guys, I successfully added a new column in the Access Database for Hole Clearances.  I wanted a fit that was the "next size up" being roughly 1/16 up in size, except for smaller sizes, but I can't figure out how to get solidworks to recognize that there is a new column.  Is this possible through the API or ?  Any help would be greatly appreciated as If I can get it solved, I will document and share the process for everyone else, (see pictures below)

Sincerely,
