I would like to pick from the list when the PO is initiated. We have been putting in additional lines on the purchase tab for the same vendor but having a different manufacturer. This may not make sense but in the electronic components world, the same component might be made by a dozen different manufacturers and any one of them is suitable. Sometimes a component isn't available so we move down the list to the next alternate, regardless of price. The next order might be the opposite so we want to preserve ordering data for each alternate. This idea doesn't work at all in Odoo because it mandates that you go with the lowest price. This is a fail, in my opinion. For our purposes, there's no point in having multiple choices if you're not allowed to choose them.
