as far as I know, not for a single trade, the issue is to know which trade you want to partial close, no 3rd party product will know this, only you as the trader, this is why you need to do it directly from the platform.
One option is to open a trade with a label name and use this to close, but that's still too slow for you.
The smart scalping tool will only work for you on a single trade if you have just a single trade open.
