Trying to add Cointracker CSV file, but get this msg: It looks like your file has too many transactions. The transaction limit for CSV files is 1000. How to fix?

The Turbotax informational post says there is a 2,250 transaction limit in CSV, and CoinTracker says they aggregate to that number or lower as part of their partnership with TurboTax, but the online entry limits to 1000.
