When the United States files separate land condemnation actions and
concurrently files a single declaration of taking relating to those separate actions,
the Clerk of Court is authorized to establish a master file so designated. If a
master file is established, the declaration of taking shall be filed, and the filing of
the declaration of taking therein shall constitute a filing of the same in each of the
actions to which it relates when reference is made thereto in the separate
actions.
