[FR] Multiple conditions?

[javiertury]

Is your feature request related to a problem? Please describe.
I would like to create a condition for any event in a selection of calendars. The goal is that whenever an event in a calendar is occurring, the device enters "do not disturb" (DND).

Describe the solution you'd like
I would like that the calendar condition allows selection of multiple calendars, or even better, that one can create a composite condition using OR/AND rules over other conditions

Describe alternatives you've considered [optional]
I've tried turning on DND whenever an event in any calendar of interest starts, and turning DND off when any of said events finishes. The problem is that overlapping events make this scheme unreliable and erratic.
