Why can’t the away settings have a more detailed programme?

Annoyed

I really don’t want to waste money heating the house when I’m away but it appears I can only set the away settings to have one temperature maintained 24/7 ..... that is without editing within EACH ROOM & EACH TIME PERIOD when I want the home/away settings to be ignored.

Setting the timers at the start of winter and the end of spring is a MAMMOTH job.

I wish I could save the winter settings separately...
