Someone mentioned it earlier but would it be possible to add a purchase price field when adding a manual balance?

Then the purchase price could be weighed against the current market price telling you if your investments are in profit or not.

As is stands right now my balance and profit and loss are always the same because I don't use ledger entries.

If you can't do it for the whole portfolio it would still be cool to see how much i'm up or down on each coin based on where i bought in.

Maybe a checkbox if the wallet is for mined funds so it knows it's always 100% profit.
