Target and stoploss in Percentage

hi , currently when we place a cover or robo order , we have to type stoploss and target in Price , this is good but when trading on small target the LTP keeps changing so inorder to place an order we have to again change the stoploss and target , but if there is an option to change it to Percentage , we an simple use that , for example we can set 3% target , 3% stoploss , so placing order ll be way easier and safer
