When the municipal governing body approves of an amendment to a license which would change such terms of the original license as are affected by schedule 1, 2, 3, 4, 6 or 7 submitted with the application to amend, it may amend the original license by attaching thereto a duly authenticated rider bearing the seal of the municipality, if available, or on the official letterhead of such licensing authority. When the municipal governing body amends a license so as to extend the effective date therein to authorize any subsequent occasion or occasions requested in schedule 5, such license shall be returned and a new license issued.
