Based on the patch notes it seems that you should also be able to do custom delivieries to M'Naago in Rhalgr's Reach. Presumably you will be able to deliver 6 items to her in addition to the 6 items to Zhloe.
To unlock the delivieries to M'Naago it seems you need to reach some point in the MSQ, so I would suggest you work on the new MSQ quests and see if any of those unlock the custom deliveries.
