Marking items as Picked automatically reserves if sufficient stock is available at default location when multiple locations exist

We spend hours every week manually picking products - imagine having to go through over 500 line items daily to pick wire and trim parts. We need accurate counts on the vans so these parts exist in multiple locations - The new under Inventory Settings " setting Marking items as Picked automatically reserves if sufficient stock is available and checks out when item exists in a single warehouse location" works great but hoping a new setting can be created that "Marking items as Picked automatically reserves if sufficient stock is available and checks out when item exists at the default warehouse location and picks from the default location.
