Can stockpile-priority influence hauler-priority please?

So ik i suggested something like this in the global-settings suggestions, but maybe an "easy"/elegant way would be to tie the priorities of haulers to the priorities of certain stockpiles?

I have like several thousand coppers which are mostly stored away, but my haulers still haul mostly coper into the stockpiles while my mealbeans are rotting on the field (again, using the rush-command would set everyone with hauler-job to cary them which i dont necessarily want). If i set my food-stockplie to highest priority this should make my haulers always priorize the food-items that are set for that stockpile.

Edit: I tried rushing it now, and my haulers still carry copper, iron and stone, but the guests seem to prio the mealbeans?! Might this be buggy?
