Promotion/Relegation and minor league teams
 

So I set up a custom Pro/Rel save with four leagues/tiers, top and bottom 3 teams get promoted and relegated. Each league has a AAA, AA, A and rookie league.

The problem is when a team gets promoted from say, the fourth tier to the third tier, their minor league teams remain in the fourth tier's minor league system. Is there a way to automatically have minor league teams move from tier to tier just like their parent team, or would I have to set it up in a certain way to have that happen? Right now I have to manually move each minor league team at the end of the year and it gets tedious
