Match prep. for reserve and youth team

I noticed that you cant control the match prep. for reserve and youth teams unless you take control over the teams.

I always lower the mach prep to lowest possible as soon as my bars are fluid.That way my players will only spend 10% om match prep,and 90% on actuall training.

This year it seem that you have to take full control over the reserves/youth teams if you want youre players to develop max.Cause if you dont they will only get 70% training trough the whole season,cause of the 30% automatic match prep.

Is there something I'm missing here,or is this working as intended?My youth team really dont need 30% mach prep ....they need 100% training.

I think it would be nice with an option to lower match prep for reserve and youth teams,and still let youre ass man and coatches control them.

This really should be fixed.

So I guess my question is : will youngsters develop more if you take controll of youre youth/reserve team?Cause this seems to be the only way to give them maximum training.(10% match prep./90 % training)

Or will they develop just as much with the default 30% match prep./70 % training?If not,this years fm will be very time consuming if you want to develop young players to max in a long term save.
