How do I close position separately?

Hi guys, can't seem to find a way to close my position separately. I'm using USD-M Futures. For example I bought BTCUSDT at price 40000 and my position size is 0.1 I'm planning to hold this one for a long time. My target profit for this position is 50000.

Then there's an opportunity to scalp in 1minute timeframe, so I place another order at 46000 and my position size is 0.9. With risk management, this time I set a tight stoploss therefore my position size is big. My target profit for this position is 47000.

In Binance 2 different order with different entry point but same currency will be mix together in the position tab and it will say Size(BTC) = 1 (0.1+0.9). When the price reach my desire Takeprofit, if I choose the close position option and select size 0.9 the +profit will be all wrong since it might also close my 0.1 position at 40000 entry price.

So my question is, are there any way (without setting SL/TP beforehand) I could close my 0.9 position at entry price 47000 seperately without ruining my 0.1 position at 40000? Thank you.
