This would be more convenient rather than to have to hover the mouse on the recipe in the scan window.
And to then manually set the correct tier for each reagents one by one and finally setting the finishing reagent.

I will definitely revisit the possibility of adjusting default crafting ui mats automatically and then maybe think about implementing smth like this

you mean to load the reagents into the default ui so it can be crafted?

Yes indeed.

Thats a bit problematic. I tried to do this in an earlier version of craftsim but it leads to the blizzard ui bugging out and not allowing to craft more than one item at a time
Thats also the reason why the reagent optimization only can assign the reagents in simulation mode and not the default ui

I can try to take a fresh look at it though

but you can always just shift click it to put it in the craft queue and then press on craft

you can even enable a craft queue option to make it always appear when you put something into the queue

Oh that's a bummer, I hoped it could be done...
Hopefully it gets fixed and you'll be able to do it at some point.

Regarding the limitation to craft one item at a time, it wouldn't be a problem for me.
I mostly only use the single craft button as the craft all button doesn't seem to mind if you run out of concentration.

I never actually tried it but as I saw that the number shown wasn't updating with and without concentration enabled,
I assumed that it wouldn't stop when concentration runs out and that it would keep crafting regardless.

And as a side bonus this allows me to be more in control and to fix things if I ever screw up the first craft for whatever reason.
