Okey, I've got an idea which I think would be very useful.
At the tactics screen, you should be able to select target man and playmaker by position, and not just by player. For example: If you use a 4-2-3-1 formation you of course want the one striker to act as the target man. Then you could simply select Target man: ST, instead of having to chose the stiker who happens to be picked for the game.
This would also work excellent with playmaker and throw-ins.
Here's a picture of how I've imagiend it to look:
Simply enough, you would just right click on the position of your choice, and select the role from the menu. My photoshop skills are not the best, but I hope the message got across.
