International Management, quit/sacked by the club, Option

Just an idea but when you get offered an international job it would be nice to add an option to 'Accept and leave club position' or perhaps have a warning 'the board is unhappy that your commitment to the club and will consider your position/sack you' (similar to when Freddie Shepherd blocked Robson from England)

It just seems slightly unrealistic that if your a full time top flight manager competing in up to 5 competitions that you could lead an World Cup qualifying campaign or that the FA would be happy with that
