Just following-up. The AltCoin.io importing of APIs and CSVs isnt perfect but it's automatic and free. (At least it's free now although there has been discussion of a premium service).
I'm currently pulling in both Poloniex and Bittrex APIs. They are working on Coinbase integration and it is almost ready for release.
Quite happy to have found AltPocket.io. It's easier for me than visiting CoinTracking.info and manually importing.
