Create a Custom View

I know this is similar to a couple prior posts, but I wanted to do more than simply upvote. I'd really like the ability to define a new view for my portfolio(s) by specifying the fields (selected from all those available on the various currently defined views) and the field order and to have that view retained and easily recalled under a name of my choosing. Bonus points for supporting the definition of calculated fields.

Thanks so much for your website.
