It actually wasn't (isn't currently, at least to me). In the lend-lease window after you select what you are going to send (i.e., all that captured equipment), if you mouse-over the picture for the item it will show you what you have in your stockpile in the tooltip.Oh, and the lend lease one is my favorite. Why? Because I often try to lend lease out ALL of my old or captured equipment and it's a pain to get the numbers lol.
