If you want to separate this for being in position and out of position on the turn in a HUD statistic you can change the properties of the statistic in the 'Item Properties' tab at the top right of the HUD Profile Editor window. Select the stat you wish to configure and scroll down to where it says 'Has Position'. Bear in mind that this is for either in being position (last to act) or not being in position (not last to act) so in multiway pots the player may be out of position but still in position relative to the preflop aggressor so if you need to be more specific you would need to create custom statistics for that - see
this guide for the basics on custom statistics creation and
this guide for a deeper walkthrough.
