Currently you can set up a timer under the "Quick" mode or you can block timespans from days of the week under the "Daily/Week" mode. The timespan you set for a given day of the week gets saved in your weekly plan unless you manually delete it.
I would like for there to be an option to block the current day from 7am-7pm or 8am-9pm etc without having to format the weekly calendar each time.
Another workaround would be to create a button that easily resets your weekly schedule so you can just select day you want without having to delete information from previous days of the week.
