B. The plaintiff may, alternatively, receive a final, appealable judgment for possession of the property unlawfully entered or unlawfully detained and be issued an order of possession at the initial hearing on a summons for unlawful detainer, upon evidence presented by the plaintiff to the court. At the initial hearing, upon request of the plaintiff, the court shall bifurcate the unlawful detainer case and set a continuance date no later than 120 days from the date of the initial hearing to determine final rent and damages. On such continuance date, the court shall permit amendment of the amount requested on the summons for unlawful detainer filed in court in accordance with the (i) notice of hearing to establish final rent and damages mailed to the last known address of the defendant and filed with the court at least 15 days prior to the continuance date as provided herein, (ii) evidence presented to the court, and (iii) amounts contracted for in the rental agreement. Nothing in this subsection shall preclude a defendant who appears in court at the initial court date from contesting an unlawful detainer action as otherwise provided by law. If under this section an appeal is taken as to possession, the entire case shall be considered appealed. The plaintiff shall, in the instance of a continuance taken under this section, mail to the defendant at the defendant’s last known address at least 15 days prior to the continuance date a notice advising (a) of the continuance date, (b) of the amounts of final rent and damages, and (c) that the plaintiff is seeking judgment for additional sums. A copy of such notice shall be filed with the court.
