Cost basis for shares including dividends paid?

Hi,

Is there an option or a place to see the cost basis of shares that take into account the dividends paid by these shares? (i.e. the original cost basis of the shares being reduced by the dividends received)

If that’s not there, it would be nice to be able to have another overlaid plot on the securities Chart showing the cost bases reduced by the dividends just like the current price paid changes with new purchases or sales.

Maybe not for calculations but for a visual representation of the current state of a security on the Chart, including the dividends.

I don’t think there is, but since there is a total dividend, you could subtract it in your head.
