Send tender notification to supplier - OTM

Hi all,

I wanted to share a client request with you. As you may already know, they would like to send an email to each supplier involved in the shipment (involved party = SUPPLIER) upon tender acceptance.

More specifically, in the case of multistop shipments, each supplier should receive only the details related to their own ship units, without visibility into the orders belonging to other suppliers.

Is there a way to create a dynamic stylesheet that can identify the specific involved party receiving the email?
This way, we could potentially use a conditional IF logic based on the stop location or something similar to filter the relevant data.
