I am trying to use "CSV Import" to create multiple subtasks under multiple parents.
For example,
1. Parent (Story) 1 (Summary: Kevin)
-> Subtask A (Summary: Kevin - Subtask A)
-> Subtask B (Summary: Kevin - Subtask 
2. Parent (Story) 2 (Summary: Chris)
-> Subtask A (Summary: Chris - Subtask A)
-> Subtask B (Summary: Chris - Subtask 
3. Parent (Story) 3 (Summary: Andy)
-> Subtask A (Summary: Andy - Subtask A)
-> Subtask B( Summary: Andy - Subtask 
Those three Stories have already been created, and now I want to use CSV import functionality to create those 6 subtasks.
Is it possible to copy each parent's summary to the subtasks that will be imported by CSV?
For instance, in the automations, I know there is something like {{issue.summary}} to copy over the trigger issue's summary, but I am not sure how to do that in CSV import function.
