Can it possible add a column for close order position size by manual

I know MT4/MT5 is design to trading FX.
But some broker provide their MT5 for trading Futures.
With futures there is a rule FIFO , so broker only can set their MT5 to the netting mode.
It will cause only can running one EA in one symbol. Because new order will cover old order(include magicnumber and note).
See my attachment video.
That's mean one of all EA will close all position by them self. 
So, I want to ask for a feature change both in SQX and Algowizard.
Can it possible to setting Exit order size when I close the position by manual?
I think there is the only one way to resolve futures trading problem.
Thank you.


But I think there is no way to resolve " stoploss, takeprofit, movesl 2 be, trilling stoploss" with MT5 netting mode.
