How do you handle transfering conjured water/food in the team?

[MiRai]

1. Conjure up some food and/or water
2. Open up the trade window with whoever I need to trade with
3. Put in the amount I'd like to give them
4. Turn on mouse repeater
5. Click trade simultaneously on both windows
6. ???
7. Profit

Using InnerSpace and ISBoxer of course.
