Question

I create a work schedule here: https://NAME_COMPANY.bitrix24.ru/timeman/schedules/
I need to specify that employees can work either from 9.00 to 18.00 or from 10.00 to 19.00, how can I do this?
None of these options seem to work:

1. Free - you need a fixed one, there is no time at all
   
2. Fixed - here you can not do either or, only a clear time ..
   
3. Shift work - can be done if there is an agreement that the employee works 2 days from 9 and 3 from 10 ..
