A simpler solution will be for the manager to temperorily quit the association before the draws are made and then rejoin after the tournament ends.

Lets be realistic its too much hassle to implement these suggestions considering the few people playing the finals. Much fewer even see it as a nuisance since they joined the associations volontarily.

By the way i dont see how it will be disadvantage to anybody since association matches dont use players condition.

Just my 2 cents
