After obtaining Trained Eye I feel there should be an option (like a toggle or something) you can select while performing quick synthesis to guarantee hq crafts. Maybe have it like a togglable skill similar to Fisher's Collect where it just automatically subtracts the CP but items start at 100% quality or something. I don't really care the form as long as the function is represented in some way.

If I need a whole bunch of the same item crafted at high quality, it can get very tedious having to do each craft individually when I'm just hitting Trained Eye and one or two Synthesis actions to complete it.

I feel like only enabling the option for recipes that Trained Eye can be used on (10 or more levels below you) doesn't really break anything balance-wise and would save so much more time.
