smart stop out, new rule

In the case of a "stop out", I would like to be able to define in advance which positions are to be closed and thus define the order in which the positions are to be closed. (for example as a stop-out rule, or something similar)
This would be of enormous benefit to the trader and would represent the same risk to the broker as if the positions were closed by the automatic smart stop-out.
I am thinking that if the trader did not define such a requirement, the existing rule would simply apply, or if the positions to be closed defined by the trader were not sufficient to maintain the required margin, the existing automatism would take effect.
I believe such an instrument would make trading through cTrader more attractive. This would allow traders to trade closer to the limit without worrying about which positions will be closed and which will remain open.
The result would probably be more intensive trading because the risk can be defined to a certain extent.
I would very much welcome an extension or a supplement with such a function.
