Removing trades made in the past

I am reviewing my trades and came to the conclusion that I made a trade that had been run over the weekend, this is a hard no go, even if this is a profitable trade it’s not oke since it can gap over my sl and cause major damage to my acount. Now it would be really nice if I could remove this trade without having to got back in time on my backtest which wil cost me a lot of work since I have to redo a lot of trades.
