Same item, different vendors - I need separate vendor numbers to show up on POs

Same item, different vendors - I need separate vendor numbers to show up on POs

I have an item I order from multiple vendors.  Each vendor requires us to submit the order with the vendor ID number on it.  I have these entered as custom fields on items.

But I can't make separate templates with these numbers added.  I can either add the item custom field to all pdfs or to none of them.  Is there a way or a way on your roadmap to have item custom fields added to PO templates so I can easily make orders for different vendors?

Thank you.
