I am long time Quicken user who altered Security Type list years ago. Quicken uses my altered list without problems except with attempts to use Morningstar data. My Mutual Fund holdings in Portfolio View display Morningstar Fund Category and Category Rank but not Morningstar Rating, Return , or Risk.
