I have 30 smart plugs and 3 smart bulbs .  I have set up an operation schedule for each ( maximum of 32 different instructions, each with its own switch) . If I want to stop or start the switching schedules in all these devices I have to individually operate over1000 switches!! My suggestion is for an on off switch for the device schedule which would massively reduce the number of switches I would have to operate from 1056 to 33!!
