Hello,
I am Trying to find where/how to add a new “ERP Field / Value” to the BC202000 screen. We would like to be able to push an attribute with the “ERP Object => Template Items → Matrix” like we are able to with the “Template Items → attributes”.
Or we would like to be able to push a custom field on a matrix item so we can push our UPCs to Shopify.
How can I add custom fields to this dropdown?

I’ve been looking through the PX.Commerce.Shopify source, but as far as I can find it pulls the values out of the ether.
Thanks in advance!
