Idea of Partial Exit in Cover-Order (CO)

Hi Traders

Is there any feature for partial exit from Cover - Orders (CO).??

What I mean is … suppose I am long 1000 Infy.
Now infy is giving 10 points profit .
So instead of exiting full 1000 , I will exit 800 at market price.
remaining 200 is till trading with with original SL.

I know about BO . but i think its useless in scalping.
when the moment is right , we need to enter fast … whats the point giving market buy/sell orders.
and also it takes time filling bracket order … giving bad enteries or missing.

In CO partial execution is not possible once main order is executed.
Only option is to enter order multiple times as once order is placed one cannot modify quantity but only prices accordingly.
