New LedgerX user here. I saw in the LedgerX FAQ [here](https://support.ledgerx.com/hc/en-us/articles/360046330113-Does-LedgerX-provide-tax-documents-) that LedgerX is now providing 1099s at tax time. My question is how they can calculate cost basis for BTC that were transferred in from another account (e.g. Coinbase). Is there a way to import cost basis from the other account? Thanks in advance.
