Passing corner instructions

[Fortiscataphractus]

I wish there was the possibility of telling a players to pass the ball to the centre rather than head it inside during corners. This would allow for more creativity and a greater sense of tactical control during the match. Additionally I believe corner routines should have a familiarity factor as tactics do.

What would you expect for the outcome of a set piece routine to have a full familiarity, comparing to a 50% familiarity routine? This is so we get to understand the reason by why you would like to add familiarity to the game.
