Can Supplier Portal Page be Customized With DFF's From Purchase Order?

Content

I want to be able to create a Purchase Order DFF and see that information in Supplier Portal.

I read the note in Oracle support: Can Supplier Portal Page be Customized With DFF's From Purchase Order? (Doc id 2411317.1), and it is not clear for me.

in the note said: a) it is not possible to customize the Supplier Portal page. b) PO page can be customized so that the DFF’s are only visible to someone having the Buyer Role. This will then dictate the same DFF visibility on the Supplier Portal page. To do this, create a custom expression at PO line level and stipulate the DFF’s visibility only when user has Employee role.
