Today if a user tries to input a JQL query for planned stories, Zephyr Enterprise does not enable the save button because 0 results are pulled. The situation where a user would have 0 results could be because stories that meet the criteria have not been created yet in JIRA. The JQL queries are consistent across releases. (A difference could be March vs April in the selection criteria, for example.)
The enhancement would allow a user to save the JQL query. Then as stories are created in JIRA, the information is pulled as expected when the sync occurs.
