Version: DocumentFormat.OpenXml v2.20.0

I am working on an issue where the customer has reported that it takes a while for the DocumentFormat.OpemXml.Packaging.SpreadsheetDocument.Open function to determine a large Excel document (329 MB) is invalid over the network. Is there a plan to be able to pass a CancellationToken to the open function?

The function is passed a System.IO.Stream input like this: using (SpreadsheetDocument Doc = SpreadsheetDocument.Open(input, false))
