FM18 Swap position player instruction - where is it?

..I'm not seeing this. can anyone give me very specific walk through of where it is? I've tried the tactics > players > position and it isn't there. I've looked on player instructions and it isn't there. You say it's at the bottom of the player instructions but it isn't there for me. I have cross aim and cross frequency but that's it

Not at the game so not specific walk through sorry:
It doesn't appear to be available with the Personalised Instructions in the PI window, but it is, I think, available for the positional instructions. So you can have positions swapping during the game, but not specific players.
