Will you make it so that crafting materials stored on our retainers are available for use (automatically) during crafting?

What I mean by this is: I have 99 iron ore on one of my retainers and 0 iron ore in my inventory. I want to make an iron ingot for a crafting leve. I am at Hawthorn Hut. I want to be able to craft that iron ore, at hawthorn hut, without going back to the city to get the materials off my retainer. When I open up the crafting window, I want it to recognize that I have 99 iron ore -- even though it is not in my personal inventory. When I click synthesize, I want it to remove the iron ore from my retainer and consume it to make an iron ingot; and I want that iron ingot to go to my personal inventory when it is finished.
