Trade History Improvement - Show partial profits as 1 trade

There is quite an important issue with how trade history is displayed.

For ex.

If I go long on the SP500 with 10 contracts at 2500

Say it rises to 2505 and I want to close 4/10 contracts. If I do and then close the remaining 6 in the trade history they appear as 2 separate trades and as such dilute any sort of trade reporting.

It would be good if you made it appear as one trade like MT5 does
