In the expense sheet, under the Menu section, each row has a green vertical double-headed arrow. When the mouse cursor is placed on it, it shows Move line to another project. This arrow is used to move that particular row to another project in the expense sheet. This helps in entering all the expenses first and then moving the specific rows to its associated project and when the arrow is clicked and the specific project is selected, it creates a new expense section for that project, and also adds the row to it.
