Setting Weekday/Weekend notification rules?

I’ve got the Pebble Time 2 and when I get a notification on the watch, I have several options to mute notifications from that specific app, including Mute for 1 hour, 1 day, weekends and weekdays. However, on my mobile app (iOS), there is no equivalent option that I can find. If I do select one (like “mute weekdays”) on the device, that status will display in the mobile app, but I can’t change it. Am I overlooking something? How can I properly manage these advanced notification settings from my phone? Thanks
