The toggles shown above let you switch between whether the player is using instructions for everyone in the position, or instructions specifically designed for him.
If you have created personalised instructions for a specific player, he will always default to those instructions if played in a position. If not, he will use the default.
So if you have a striker who you always want to be a target man, you can give him personalised instructions and your tactic will automatically change that role to target man.
