"Load into Transport" button

Add a new button in Command Bar ( with keyboard shortcut) to have the selected unit(s) to search for, and enter in the nearest vehicle with Passengers= set that is not yet fully loaded ( to execute Script 14 from in AImd.ini's Scripts )
This isn't related to modding, but would be a good enhancement for the game, especially for players who use many Battle Fortresses / Flak Tracks, or for water-islands, when you need to load a lot of units into transports.
