A witness for the Commonwealth in a criminal case shall be entitled to only one (1) witness fee per day and to mileage for only one (1) round trip per session, regardless of the number of cases for which he has been subpoenaed and regardless of the number of days he appears in court. Where the witness has been subpoenaed for more than one (1) case, his fee and mileage shall be prorated among the cases for which he has appeared during such session. It shall be the duty of the Clerk of Courts to keep a list of the witnesses and of the cases for which a witness has appeared. The Clerk of Courts shall charge and prorate the witness fee and mileage in accordance with this Rule.
