CTrader Mobile - setting SL and TP through price point

In the CTrader Mobile App when placing an order please include the option to define a stop loss or take profit not only by setting pips but also by setting an actual price point alternatively.

Obviously that couldn't be that difficult: Once a position is opened, in the "protect position" field you can set or modify an SL or TP by changing either pips or alternatively the price. Why ist that not possible when placing an order in the first place? Also, the desktop version has it too.

Thanks!
