NEED: Ability to enter inputs with multiple supplier sources/purchase prices Merged

When adding a new seed variety or a crop protection product, the software only lets you assign one purchase price per input. This is a huge problem for many producers and makes it rather unusable, as in order to track an accurate cost of production they need to be able to add multiples of the same varieties of seeds with each having a different cost. Right now they have to either have a fake input to track the cost or do an innacurate average. This is an extremely important feature that must be added ASAP.
