JIRA integration Import of only linked epics

When stories in JIRA are moved between epics they are not automatically updated in aha. Also, for stories created prior to mapping a JIRA epic the stories are not automatically imported to aha. The import can be used to pull these in but the Import will import all epics and associated story in a project. We would like to have an import option that allows us to update all epics already associated with an Aha object. This would bring in any associated stories.
