MLB Quickstart w/ Feeder Leagues?
 

Can't play OOTP 19 until the weekend; so forgive me for asking this.

Rather than having go through the hoops of having to create a standard MLB league (and having to add the minors, etc), is there an easy way to add a complete feeder league system to the current MLB quickstart without breaking anything else?

Also, I would like to add the Japanese, Korean, Cuban leagues along with the World Cup of Baseball. Can I do this in the quickstart?

a) Would I have to make any adjustments to the international FA system (E.G so that I won't have two tiers of Japanese players entering the MLB, 1) through the Nippon league and 2) game generated intl FA)

b) will the posting system be automatically integrated, or am I supposed to add anything to it.

Thanks
