Inserting taxonomy into Packing List

I’m having a difficult time inserting a taxonomy tag, of a custom post type, into a column on the “custom picking list” template. I’ve searched through other support tickets and the website, but I just cannot seem to figure this out…

here’s the post type URL string:
/edit-tags.php?taxonomy=product_brands&post_type=product

where “product_brands” is the custom post type

###

I’ve pulled the record number (attribute) out just fine, but keep failing on every combination I’ve tried for the tag/taxonomy. …I feel as though I’m just spinning my wheels and going in circles now.

I currently have this, which isn’t correct:
|product_attribute=product_brands|product_attribute=pa_record-number|

here’s a screenshot of the void that I’m trying to fill:

and as a side note, if (for example) I needed to pull “Book Publisher” for books OR “Record Label” for records, is there a way to insert one or the other… since there would only be 1 chunk of info (either Publisher or Label, but not both)?

does that make sense
