Reject individual lines by supplier

Hi, I have a requirment in Sourcing Cloud for negotiations where we need to be able to reject individual lines per supplier without rejecting the entire supplier during the technical stage anaylsis so that the client cannot see the item form that specific supplier during the economical stage if the line didn't complied with the technical requirements.

Until now, I've only seen the posibility of rejecting the entire supplier, but only an specific line of a supplier bid.

Does anyone know if this is possible or how can we manage this situation?.

Thanks!
