Adding dot permanently into the rectangle drawing box

hiii I really love to use CTrader and I hope in future Ctrader will consider adding a dot permanently in the middle of rectangle just like in mt4 , i use this rectangle drawing a lot and it would be very helpful to draw rectangle n find out its 50% retracement real quick. Pls view the picture below, it's something like this from mt4 ( the middle dot won't disappear , it'll be fix there , so easily i can mark horizontal line on it ) , but currently cTrader rectangle has it in both sides and it disappear when cursor is away from the rectangle box!
