Currently if I open a new position for Company X with two shares, then add another share a week later, I then have a three share position (and showing a combined P&L).
Is it possible to open a new position on Company X for two shares, a week later open a seperate position for Company X for one share, and have two position open against the same market - with a seperate P&L, and the option to close one position without closing the other (or impacting it in any way).
