Now it's possible to define time period for each day of week like:
From Monday 20:00 till Tuesday 08:00
And to exlude all working week you need to add 6 Service\Downtime times.
Also you can't define weekend time like:
From Friday 20:00 till Monday 08:00
You need to split in 2 periods.
It can be more comfortable if we have ability to define recurring periods in more comfortable way like "every day\week\month" or even working\non-working hours.
Or at least remove the "beginning" and "end" of the week with the ability to determine the period from Friday to Saturday for example.
