I'd like to have all my activites listed in one place, instead of regular daily schedule on paper on my wooden clipboard, things I'm afraid I may forget on my phone with its reminder chime and things I hear of while I'm out and about on my paper pocket calendar. The problem is that, with my daily schedule all laid out in my phone, when I try to delete one item one time to substitute a special event, the screen says "Delete X?//This and future events//All events." If I try to put in the special event by editing the regular one, it says "Details//Change all events in the series//Change this and all future events." Is there some way to put in something I want to do instead of what I usually do at that time? I have a UMX U683CL, whose OS is, I believe, Android Go 8.1.
