'Relate Ticket' Functionality

We would like to be able to relate multiple tickets to each other without the caveat of one resolving the other, much like JIRA functionality. Current Workfront functionality is Task -> Task Details -> Task Relationships -> This Resolves (hyperlink to resolving ticket). This works, but sometimes tickets don't need to resolve each other. There are many scenarios where another task may house a similar issue that we want to relate for tracking/posterity's sake, but we don't have a good way of doing that at the moment.
