As far as I am aware, there is no way to view detailed information about a package from the DIAD. Specifically, information like the weight and dimensions. I find this pretty pathetic. You can store gigabytes upon gigabytes of porn videos on a chip the size of your pinky nail, but they can't have this information sent to your DIAD along with EDD? How many times have you been looking for a package, when it could have benefited you to know if you were looking for a 3-ounce envelope or a 130lb irreg. But anyway... Let's say they did do this, and this info was included when you viewed the details of a delivery. Any time a delivery was for one of those UPS-supplied envelopes, they could put a E next to the address. These envelopes could be loaded into a tote, rather than on the shelf, where they often fall behind or under other larger, heavier packages, and may be difficult to find in a mess. Or, this doesn't even have to be limited to envelopes. It could be for anything with no listed dimensions, meaning that it will either be a flat envelope, a padded envelope, or a bag. Would it be easier for a driver to find stuff like this?
