Grand Company Supply/Provisioning Mission turn-in number

These need to be either raised or a system implemented in order to turn in specefic ammounts

Iron Plate for example is turned in one sheet at a time! It takes so long to trade the 50 Iron Plates i have.

The process:

Select NPC
trigger conversation
confirm chat text from NPC
Select supply mission (1 down for supply, 2 down for provisoning misson)
<enter/confirm>
Confirm chat text from NPC
Select A sheet of iron plate (1-3 down depending on item, 4 down if the first 3 are already completed)
<enter/confirm>
Confirm chat text from NPC
<enter/confirm> Make delivery. (window with total number of plates turned in + time remaining)
<enter/confirm> Yes (apart from yes/no a completely empty window - why does it exist?)
Confirm chat text from NPC

Thats 12-15 actions in order to turn in one(!) sheet of iron plate.
