It would be nice to be able to save a preset standard box dimensions instead of having to type in the length x width x height every time you ship a package. Especially when we have 2-3 custom sizes we use for all of our packaging. It takes up a lot of time when shipping instead of a drop down to pick between our custom packaging. Similarly, if we are picking a certain carrier (like USPS or Fedex), a drop down with their FlatRate boxes can be clicked that already has their dimensions.
