Add a separate section on features for links to other services (could be research, notes, etc)

Any time I use Aha, there are plenty of fields to use to enter information. But, there's not really any easy way of adding links to external information, unless I add them in the description field. The description should be reserved for information, describing the issue. Links to research that back up my claims (could be any product or service really), should be placed as links, in a separate field. The current research field is too closely tied to Aha. I don't want to store all my details in Aha.
