We'll consider providing a built-in way to track the overall status of a build (whether any steps failed even if the build continued).
For now, you could use a project-level step done script event to store a flag in a temporary macro for whether any steps failed (but marked to continue building) during the build, and then at the end of the build, fail the build (conditionally build an Exit step if that flag is set).

You can report on all failed steps in a build by using XML log file format, then creating a report with the Transform XML Log action, filtering on failed steps.
