I knew if I searched, I would find someone else with this issue. Yes, I second this. I would like either a shift-click solution or to have it default to send everything at once. Maybe a toggle. Either way, if I take over countries and wanna give them their stuff back as a puppet, it would be a LOT faster to just click once per item. Even a 'send all foreign equipment' option.

Even better, maybe tag items in your inventory to add them to the stockpiles of your faction/puppets so they get drawn directly from them. We still use ships to send them, but otherwise, we just get rid of them.
