At the moment it considers higher priority patterns to be prefered, even if it means crafting things, this is generally because you might have cheaper recipe or recipe that involves using more common materials, but you might have a secondary recipe that its higher priced and only used in cases where you cannot preform the first.
In other words, it kinda depends on the recipe, and what your doing, I'm having a harder time trying to come up with cases that match your request then cases where I would prefer it do some extra crafting, to prevent using higher value items. |
