The custom card plan had a free feature open to anybody where you could find various types of races from any track using a variety of search criteria. For example, if you wanted to find all Maiden Claiming races at 6f with no first time starters. It is even gone from the legacy website from what I can tell. Looks like Brisnet threw away a very handy tool in eliminating the custom card plan.
Here is the legacy page, which itself is not up-to-date with search criteria.
