Adding a special row to a BOM table template

I am trying to customize our BOM template to accommodate the specific way we operate:

I'd like to add a row at the top of the BOM, just under the table headers, with data from the assembly itself.

"ITEM NO." would read as 0, "PART NUMBER" would read as the variable "Drawing No." (from assembly, which is resolved from \$PRP:"SW-File Name"), "QTY" would read as the text "REF", "DESCRIPTION" would read as the Description from the Assembly.

Is something like this even possible?
