A. In the event the judge to whom any family and domestic case has been assigned is absent or engaged in a trial, the judge may assign the case to any other judge of the same division who is available to make an order or hold any necessary proceeding therein, as may be proper, and enter a final judgment in the case, but it shall remain on the docket of the Judge of the division to whom it is originally assigned.

B. The referral of a case to a judge other than the assigned judge for the granting of a divorce, conducting a hearing, trial, etc. shall not constitute a permanent reassignment of the case but shall be only for that limited purpose.
