Import portfolio directly from Yahoo Finance

I manually input my trades into a Yahoo Finance Portfolio, and have done this with a couple years. I really like Portseido, but to use it I had to copy my trades from Yahoo Finance to the Google Sheet. This was a lot of effort initially, but it will be manageable now going forward.

I couldn't help but think an "import from Yahoo Finance" would be super helpful. 

Alternatively, perhaps you could support the csv format that Yahoo Exports?
