Porter Moogle Services Question

I apologize if this has been answered already. Is there any chance we'll see the storage slips turned into key items? In my opinion, it is a very tedious process with the amount of gear we have today to trade the correct slip, and appropriate items to the moogle one at a time, especially when with void watch and relic+2 equipment, many players are using a combination of storage slips for VW, Empyrean, Empyrean+1, Empyrean+2, Relic+2.

It would be such a relief to just trade the equipment that qualifies for the slips you have purchased in one transaction, and to retrieve them, I would vote to combine the three Empyrean categories making the retrieval process something like this:

Talk to Moogle > Select category [Voidwatch/Zeni/Campaign, Empyrean, Relic +2, etc] > List all items alphabetically

I understand if this may not be possible currently due to the data structure design, but it sure would be nice to see in the future!
