Hi Knix, In ACS we don't have specific functionality to create and send deliveries via waves like we do in ACC.

I suspect that this should accomplish the desired result. https://experienceleague.adobe.com/docs/campaign-standard/using/testing-and-sending/scheduling-messages/computing-the-sending-...
