Restrict access to PO discount fields

Content

Hello,

1. In 19D there was a new feature introduced, to capture supplier discount on a PO line. Is there any possibility to restrict access of that field based on role- i have a case where only SCM users are the one that should enter a discount.
2. Is it on the road map to have this functionality on requisitions as well? 

Thanks
