I think you should be able to set your 'home game' kick off time for CL/CUP and League.

So perhaps you can pick between 8:00-9:00am for home league games then 18:00-19:00 for away games.

Only reason I think this isn't done by nordeus is because it would put stress on their servers at certain times of days while at other times there will be less stress. Imagine they spread games out to balance things.
