When a Proceeding will be expedited and the interests of the Parties will not be prejudiced substantially, testimony may be received in written form. The prepared testimony of a witness upon direct examination, either in a narrative or question and answer form, may be, if admissible, admitted as evidence and incorporated in the record as if read or received as an exhibit, upon the witness' being sworn and identifying the same as a true and accurate record of what his testimony would be if he were to testify orally. The witness shall be subject to cross-examination and his prepared testimony shall be subject to being stricken either in whole or in part.
