When crafting at a crafting bench

Can you please change it so if you’re crafting at a crafting bench, that you can just pay for the basic mats you buy from the supply vendors directly while crafting?

What I mean, is say I am playing on a character with blacksmithing. I go to the crafting bench to do some work orders. Find one I can/want to do.

“Oh, I need core alloy for this one. Switch back to the main crafting menu, oops, I have no Echoing Flux.”

Then just tell it to craft as many as I want and just pull out the money for the Echoing Flux as each one is crafted rather than having to tediously close the menu, talk to the vendor, click the item for as many as we want/need. Close the vendor menu, open the crafting menu again. Rinse and repeat for as often as we need/want to craft.
