The restocking favorites feature has some intelligence regarding how many to queue — I especially love the “as many as I can currently concentrate”. I mainly use the recipe scan to find the most profitable conc value, then shift click the top entry, then manually adjust to the amount that fits within my concentration.
I would love an option to enable shift-click in the recipe scan to queue the amount I can concentrate on as well!
Additionally, it would be absolutely perfect if it also included my TSM restock string, and takes whichever number is smaller

(Example:
I have enough concentration for 4 crafts, TSM restock amount would be 100, I automatically add 4 when I shift click.
I have enough concentration for 17 crafts, TSM restock amount would be 2, I automatically add 2 when I shift click.)

Maybe a checkbox each?
[ ] Use all available concentration
[ ] Use TSM Restock Expression
