Can you show item attributes in iSupplier?

We are sharing our forecast with the suppliers for items using supplier scheduling. However, there are only certain parts that we want the suppliers to make per the forecast - the others are only for FYI purposes. The items which fit this criteria have been identified with a unique planner code at the item-ORG level. Is there a way to show this planner code on the planning tab in iSupplier? We are currently using EBS 12.2.3 version.

Thanks
