Concession Revenue (from users & buyer) - No identified element

there should be a way to mark information like

• Concession Revenue User
  The estimated revenue coming from the users of the concession (e.g. fees and fines).
• Concession Revenue Buyer
  The estimated revenue coming from the buyer who granted the concession (e.g. prizes and payments).

This information is linked to the winning tender, so I would expect it in the AwardedTenderedProject; should each of the two values go into a TenderLine, should specific terms be created or is there any specific element?
