(1)    Consolidation.

      (a)    When actions which might have been brought as a single action under s. 803.04 are pending before the court, it may order a joint hearing or trial of any or all of the claims in the actions; it may order all the actions consolidated; and it may make such orders concerning proceedings therein as may tend to avoid unnecessary costs or delay.

      (b)    When actions which might have been brought as a single action under s. 803.04 are pending before different courts, any such action may be transferred upon motion of any party or of the court to another court where the related action is pending. A conference involving both judges and all counsel may be convened on the record as prescribed by s. 807.13 (3). Transfer under this paragraph shall be made only by the joint written order of the transferring court and the court to which the action is transferred.

   (2)   Separate trials. The court, in furtherance of convenience or to avoid prejudice, or when separate trials will be conducive to expedition or economy, or pursuant to s. 803.04 (2) (b), may order a separate trial of any claim, cross claim, counterclaim, or 3rd-party claim, or of any number of claims, always preserving inviolate the right of trial in the mode to which the parties are entitled.
