Import Sales Pricing via REST API

I am trying to update Sales Price pricing via the REST API. There is no endpoint that I could see that will do this (there is the SalesPriceInquiry) – which seems to create the price if it does not exist, but it does not update. Is there a way to get it to update the price?

I’m sending:
 

SalesPriceDetails": [
    {
        "EffectiveDate": { "value": "05/02/2024"},
        "PriceType": { "value": "Customer" },
        "PriceCode": { "value": "1000346" },
        "Price": { "value": "12.99" },
        "InventoryID": { "value": "OURSKU" },
        "Warehouse": { "value": "CA" }
     }
]

But, I am getting the error:
"error": "Duplicate Sales Price. This line overlaps with another Sales Price (Price: 10.990000, Effective Date: 5/2/2024, Expiration Date: )",

Is there a way to tell it to update if the price exists?
