This issue will be that a saved table to table import can only be at the detail record level, but Ashley wants to copy across a summary report. I often wish I had the same feature as a Summary report can be used to create an index table of unique Key fields as a Parent to detailed methods.
The only way I know how to do this would be to have an automation or an action to add a record to the Parent index if the detail is added and there is no parent. But that would probably fail if a bunch of detail records were imported causing the webhook limit of 10/second to be exceeded.
