Provide access to stocks with incomplete data

In a recent email exchange when I was looking for a missing stock, you mentioned that stocks go in and out of the database due to old or missing data. I totally agree that 99% of the time we want full, accurate data from you. However, I maintain a watch list of more speculative stocks and having your data sometimes be there and then not be there next quarter really messes with my dependence on you. Is there a way to have some kind of flag that could be set to allow the download of all stock data including the outdated info? I assume it would default to "off" so that this does not mess up most uses for most people, but would allow people like myself who import your data into my personal spreadsheets a way to continue with the appropriate warnings?
