Set custom Date Range for the Portfolio Overview

It would be great to be able to set my own date range from when till when I would like the chart to show me the data. Right now I gotta be a sniper at finding the correct dates in order to see how my portfolio has performed during that period of time. This is something I would expect to be implemented natively and should not be hard to fix.

Would you be willing to add that as a comment here? More Sorting Options
