Can I delete a placed order event?

For context we manage several different websites through one CMS. One of which deals with most parcels with an average order value of around £20, with the other websites normally being around £300 an order. An order was msitakenly put through the parcel website on the CMS, so has come through as a placed order event on Klaviyo for about £300. It has counted this as revenue for an tactical email today  which massivley puts out reporting. Is there a way to manually delete this event and fix reporting?
