Include other attributes for search of caller

[VernYerem]

Hello! I'm a somewhat new developer, and this was something I couldn't seem to find an answer for already. If my phrasing is off, please point me in the right direction.

In the caller/requested for field, you start typing and the username and email are searched. We've added a "Badge number" field to our users, and some supervisors prefer to use that to reference people. Is there somewhere where I can add this field to be considered in the search for users? 

Note: The display field needs to stay the name of the user, just looking to add the badge number to be searched as well. Meaning in the field I could type Name, Email OR Badge to find the user.

No ideas?

Thus far, I've found how to change it to our new Badge number field with:

ref_auto_completer=AJAXTableCompleter,ref_ac_columns=u_badge_num,ref_ac_columns_search=true,ref_ac_display_value=true

Adding that attribute to the dictionary entry for reference field in question changes the field to search based on Display Name and Badge but removes the email search. Also, didn't seem to update the same field that's on the catalog item, but maybe that's changed elsewhere.

To help illustrate the issue, I've changed the dictionary entry for "requested_for" and the result has been:

Works as expected in the Standard UI.
Works as expected in the Service Operations workspace.

Does not work as expected in the Service Catalog Item.

Figured it out! The service catalog item doesn't use the field, but rather a variable. Just needed to add those same attributes to the variable:
