Reporting for B2B Portals - Still nothing after identifying this 4 years ago!

We need some basic reporting functionality relating to the B2B portals.

Unless we change the sales reps field to make the orders portal specific there is no way of easily identifying (via a report), where an order came from, as we operate several portals. The critical thing we wish to understand is how much revenue each of our B2B portals are generating, so we understand utilisation and ROI.

We need an order source field or alike to assist us with isolating this, as its not possible for us to change the sales rep field as we need this going to the correct person.

Please can you advise when more functionality in regards to the B2B portals will be on the roadmap.
