When the user uploads an Excel file with multiple worksheets, and the Allow Worksheet Selection option is enabled, they're given the option to select which worksheet to upload. They can then do another upload with the other worksheet's data. But then we have two uploads of the same file name, and we have lost the context of what differentiated one worksheet from the other.

Adding selected_worksheet_name to the import_complete webhook payload would be very useful. It would be even better if, on the page where the uploader makes their choice, they had the option to give their data segment a custom name and use the Excel worksheet name as the default selected_worksheet_name.

The "Show import description option" is not really a substitute, as it appears before the Worksheet Selection screen.
