Control of Kick Off Timings for Age Groups/Competitions

Is it possible to be able to prevent teams changing kick off timings  per age group or division? in Matchday App through Fulltime?

As far as I can tell, this can only be controlled through the League Options tab and you have to set this option for the whole League.

In our League, we allow non-competative age groups to set their own kick offs times, as they control the pitches/Refs, however for the  Competative age groups the kick off time is controlled by the League due to Referee availability.

We have found Competative teams can change the kick off time without the consent of the League via the Macthday App which naturally affects the Referee.
