Display Line DFF to Supplier in Portal

Summary

Would like to have a line level DFF to have the supplier fill out

Content

Hello,

My customer would like to be able to capture additional information from the supplier at the line level during negotiations. I am able toput a DFF at the line level from the buying side but I have not found a way to capture from supplier portal yet. Does this functionality exist and if so, can someone please point me in the right direction for where to set it up?

Thank you,
Stephen Makar
