Cargo in Simulator

I must confess that I've always preferred tactical battles to the rigors of empire-management, so I was very pleased with the latest instalment in the Space Empires series. In the Demo I've mostly been having huge fleet battles with 'Alltech', however, one thing about the simulator irks me more than any other bugs and that is the cargo management screen.
When loading carriers with fighters or troopships with troops, you have to click each unit individually to load, which can take some time considering the advanced carrier can hold over 200 fighters.
What I have found is that clicking the option at the bottom of the screen to increase how many units move in groups of 10 actually just moves one of each unit you have, i.e. if you have 1 fighter type and 10 different unit types and double click on the fighter to move it across while 10 units at a time is selected, it will move the fighter and 9 of your units across.
I think this is a carry-over from the loading screen used in normal gameplay where there is a finite amount of units to move, whereas there is an infinite amount in the simulator.

Anyway, it's difficult to explain, but it would be helpful if this could be fixed by release as it is really quite annoying, or better yet, maybe someone could tell me a hotkey of some sort that works in the simulator? I’ve tried shift-clicking and the hotkeys that work in normal play but nothing seems to work in the simulator.
