Currently I have to do it in two steps. The 1st step is to import the Epics. After it's done, there are issues and issue keys for the epics. Then I need to update the Story CSV file with the issue keys just generated. I put them in the "Epic Link" column. This is to link stories with epics. Then I do the 2nd step to import Stories. Now I am wondering whether I can put the epics and stories together in one CSV file and finish the process in just 1 step. The problem is how I can link stories with epics as at this stage, the Jira issues for epics are not created yet. That means there is no Jira Issue Key to fill in the "Epic Link" field of the story items. Any idea?
