On application of a party or when the commission deems it necessary, a continuance of a hearing date may be granted. When a continuance has been granted, the commission shall set the date for hearing as soon as practicable. The granting of a continuance requested by a party may be conditioned on the ..ling of a waiver of the party's right to enforce any statutory time limit imposed on the commission.
