Possible to display Supplier DFF inside Suggested Supplier pop up on Process Requisitions page?

Summary:

Is it possible to display certain Supplier DFF fields within the body of the Suggested Supplier pop up, or in-line with the other columns, of the Process Requisitions page?

I don't see this DFF existing yet hidden within Page Composer, and unsure of any tools to add DFF's to a page if they aren't already present for me to edit/enable within Page Composer. Happy to follow instructions for another module if the same task generally applies, but I'm striking out at finding anything so far.
