In lieu of the record on appeal as defined in Rule 1921 (composition of record on appeal), the parties may prepare and sign a statement of the case showing how the issues presented by the appeal arose and were decided in the lower court and setting forth only so many of the facts averred and proved or sought to be proved as are essential to a decision of the issues presented. If the statement conforms to the truth, it, together with such additions as the lower court may consider necessary fully to present the issues raised by the appeal, shall be approved by the lower court and shall then be certified to the appellate court as the record on appeal and transmitted thereto by the clerk of the lower court within the time prescribed by Rule 1931 (transmission of the record). Copies of the agreed statement and the order from which the appeal is taken may be filed as the reproduced record.
