Portfolio view - additional features for "expand all" "collapse all"

1. Currently, those are the only 2 choices. After using "collapse all", the "expand all" button will show not only all the accounts and their associated securities, but every lot of every security. I like to see the portfolio with the lot detail hidden, and the only way to do that is individually collapse each security in each account, which is very tedious.
2. After using "collapse all", it would be nice if the sort would now work at the collapsed display level. Currently, it still sorts at the securities level within each account, even though the securities are not displayed. It should sort what is displayed, which would be each account.
