Sort swimlanes by linked issues without using extensions

[Deleted user]

Hi guys,

*Note, the solution can't include any third party extensions.*

I have a project containing the following issues and structure:

• Epic1
  • Story11
  • Story12
    • Sub-task111
  • Bug1
  • Task1 (is subtask of Story12)
• Epic2
  • ...

I have created Board1, including everything in the project, where the swimlanes are based on the Epics. That works fine.

Now I only want to create Board2, only including issues from Epic1, where swimlanes should be based on linked issues. That is, I would like the following structure:

Board2 (what I want):

• Swimlane1
  • Story11
• Swimlane2
  • Story12
    • Sub-task111
  • Task1
• Swimlane3
  • Bug1 (as it is not linked to any other issue than Epic1)

I have encountered two problems

1. How can I split Epic1 up into swimlanes as described above, since basing the swimlanes on stories would only include stories and their dedicated Sub-tasks?
   
   
2. I have used the following query for Board2:
   issueFunction in linkedIssuesOf("issue = [ID-OF-Epic1]", "is Epic of")
   
   The problem with this query is that it doesn't return Sub-task111. How should I amend it in order to do that?

Thanks!
