Yes you can, so long as the System setting Only bbookkeepers to create new rows is not selected. You can create a new row by clicking the "+" above the rows or use fast key Alt+Ctrl+N. If your only access is to Approval then any new row will automatically be sent to you as well, though you can also add other users as well. If you are a Bookkeeper as well as an Approver, then new rows will not be sent to you unless you do so and you will have to choose at least one approver for that row, whether it is you or others.
