I have been attempting to add the Mexican Liga Premier de Ascenso (Third Tier) and Liga de Nuevos Talentos (also third tier) to the Mexican League Structure for FM 13 without success recently. My idea is to set-up the Liga Premier de Ascenso as the third tier and the Liga de Nuevos Talentos as the fourth tier. That way, the promotion and relegation scheme is a bit simpler than in real life. The issue at the moment is that the editor will not allow me to promote less teams than there are sub-divisions. There are two sub-divisions in each league and, if I wanted to, I could promote and relegate two teams from each league but I would like to be as authentic as possible to the real promotion and relegation structure. Not to mention that I don't wish to mess with the default second tier structure which only relegates one team at the end of the year.
Could anybody point me towards a way in which I can go around the sub-divisions issue? Any assistance will be greatly appreciated.
