Thanks for your question and welcome to the community forum.
As far as I know, at least with TradingView, no this is not possible. Although I do believe it is configurable on other platforms.
With TradingView, you can right click your chart > trade > Enter New Order and enter additional orders as needed, but I do not think you can group existing orders/brackets as an “OCO Group” so when one order gets filled the rest cancel out. You can add additional OCO/brackets, but they will not be associated with already existing ones.
The only way to do something remotely close would be to manage these orders manually, but that is not exactly an OCO order.
I hope that helps,
