How do you simply "disable" all the schedules at once.

I have over 25+ smart plugs each with their own on/off schedules and anytime i'm on vacation or extended absense, i have to go in and manually disable all 25+ "On" schedules for each plug, then when i get back, re-enable all 25+ again. Total pain.

Scenes and Groups seem to only be useful if all plugs have the same schedule. what am i missing here?
