I haven’t used the new workflow in a long time, but doesn’t it allow you to save that information for each item so you don’t have to enter it again after the first time?
Or do you mean why do you have to enter it into the new workflow the first time you use it even though you have entered into the previous workflow? I have no idea what structure they have for these but I would guess that the 2 versions don’t work off the same database. Could they make it more convenient? Sure, but the simple answer is they really don’t care to. I’m not saying that is “right” or that I’m happy with it (I’m not) but as with many, many things on Amazon, you do what you need to do to continue to sell here.
Good Luck,
