Estimated Delivery Date Update?

Can we change the wording for when a product is out of stock and has an estimated delivery date? We are getting a lot of refunds due to the dates not being accurate. If we could add an information box when the customer views their cart on a product that is not-instock. I would like it to say “Product is shipping from the manufacturer and may have extended lead times different from the current estimated date provided. Contact us for a more accurate date”.
