The ability to add more than one pipelines/statuses to one Opportunity

This is for when the customer uses it for trialing multiple products at the same time, like seeds. If they trial 5 seeds at the same time and find out that seed 2 and 3 are not good, they would like to conclude it as lost but win for the other ones. At the moment, they can only close the Opportunity as 'win' (convert to sale), 're-trial' and lost.
