prereference daytime spread for weekly view

[Moosbueffel]

I normally use the weekly view. And I don't have events in the middle of the night. Normaly - or in some calendars - you can choose the time spread for a day. e.g. 7:00 to 20:00.

In ETAR I didn't found a configuration to this. I found to resize and scroll inside the weekly view, so I have the time spread I need. But if I leave the view and come back it's back to whole day 0:00 to 23:00.

Is there a way to configure this, or would it a feature request? In case of a feature request is there a chance to spread it automatically starting from first existing event? Do you find it usefull?
