Portfolio Graph Improvement

I like how MD puts a pie chart graph in the top right corner of the portfolio view window and breaks it down by investment types. I wish it would do the same thing when you have multiple securities of only one type, say "stock", and create a pie chart. Currently if you have multiple securities of one type, no graph shows up in the corner. The pie chart could break out the percentage of the total value for each security of that type.

Just and idea.
