Trailing SL quantity Feature

Thank you for the trailing SL feature it is great.I wanted to request to give an option to modify the quantity of scrips I want to trail my SL for. Right now when I modify my SL it takes for all the shares actively in the.

For example:-

100 shares costing $1 is = $100 exposure

now 100 shares SL at $90 = $10 risk

Now if I want to risk 50 shares at $95 and 50 shares at $90= 7.5$

2.5$ lesser.

in this way suppose a stock works out after entry we would be able to risk more money and suppose if there is a wick out not all my shares would be sold I would still be in the trade giving some quantity of the share more breathing room.
