I would like to see a feature added to testrail which allows me to associate issues/requirements at a with data structure in TestRail other than Test Cases (ie. Reference field).
This is because TestCases often support different implementations/variants of a requirement, and therefore testing of these needs to be separated and reported on differently.
A 1:many relationship exists between TestCase and JIRA - which needs to be reported and managed separately (both within TestRail and JIRA).
i.e. within I do not want to see all results for a test cases (only those under a particular testrun, testplan or even testresult level).
