Schedule Start & End Dates

Sometime last year the app was changed when entering the schedule start & end dates. The end date used to be the same or next day from the start date. Now it always selects 3 months in advance of the start date. Is there a setting to change that timeframe? If not, can the end date default to one day past the start date? I use 3-4 schedules & routinely switch between those schedules, editing the start & end dates…usually only watering 1-2 days in a row for water conservation based on needs. What used to be easy, now requires me to scroll back 3 months every time for an end date to run a schedule for 1-2 days.
