Split the inventory quantity or trade with a team mate

I've recently been playing in the squad game type. In about half of the matches I played, I scrounged up a ton of medical supplies where my team mates were unable to acquire anything.

Obviously the smart thing to do would be to split supplies with the team. When I can, I drop items on the ground for them to pick up.

Is there a more effective way of splitting up loot with your squad? Or is there some way to split your inventory count so that you can drop it?

For ex. I'd like to drop 3 of my 7 med kits so that my team may use them.
