Zephyr Scale and Requirements

My company is currently evaluating various integrated test case management systems for Jira. We find Zephyr Scale to supply everything we could want for a test case management system except requirements. Yes, user stories could be created for this, but that is rather clunky and hard to navigate. What we would like is a tree structure similar to the test case tree you have, but for requirements. This would allow for easy organization and layers of depth that are easy to see and navigate. Frankly, like RTM for Jira has. Is there any plans to implement something like this within Zephyr Scales? Unfortunately, this will be a major consideration for our final selection.
