I do not use this but incase you have to know some usefull commands.
For normal event supply.call for random and supply.drop to you. Thats the commamds and you might notice nothing if you type them but evwrything is working and do not spam commamd too many time because will call too many planes. Other command is SPAWN one. spawn supply_drop in ...
Nope you cant but there is command to call airdrop to your position or at random one, spawn the drop directly infront of you without wait to land. Also then you can spawn amd other containers ingame if you want better loot. I hope it helps.
