As a workaround, you could enter "Summary of all LT Crypto Trades - See Schedule 1" in the "Property Description" box, enter the net proceeds for the long term trades in the "Net Proceeds" box and "12/31/2018" in the "Date of Sale" box.
On the next page I'd tick "Purchase" and on the "Enter Purchase Information" page I'd enter the cost basis dollars and the word "various" in the "Date of Purchase" box.
Then go back and do the same for ST trades, answering "n" to the date acquired question.
Mail in your schedule of individual trades along with Form 8453.
