If you need to add a day to the begging of a program or reorder the days of a program, dragging and dropping full days will be a huge time saver. You will need to be in the list view to drag and drop full days. You can change from the calendar to list view in the top right of a program (this can also be done on a client's journey).
To move the entire day, you will need to click the three vertical lines and hold, then you will be able to move the day anywhere in your program.
Drag and drop into any part of the program. This can be done with blank days or with days that you want to reorder.
