Create issue linking one to one issues under "Issues in Epic" on create transition

[Teja]

Hi Team,

Would like to know how we can create one to one issue linking in Issues in Epic.

We have an automation that will create multiple issues under Issues in Epic for an Epic, so I would create an Issue linking between the issues like one-to-one mapping.

Ex:

Test-1
Test-2
Test-3

Test-1 ->blocks -> Test-2
Test-2 ->blocks -> Test-3  

Note: 

Test-1
Test-2
Test-3 

these will automatically creates, when Epic is created (Issues in Epic)

Any help?
