This may not be possible, but is there a way in ThinkorSwim to create a custom column on a watchlist to store a static data element I enter? For instance, I have a small watchlist track mutual funds in my long-term investing account in Fidelity. I'd like to put my average cost basis in this column just to see where things are at a quick glance. I also have a different watchlist of various stocks that I'd be interested in moving into once it hits a number I predetermine - if I could type in a number here to reference, that would great.
