JIRA automatoin for Project and Subtasks

[Sohail Alam]

I have Project ticket : "JIRA automation for the ticket" and Subtasks under the Project

Subtask 1: Testing ticket ABC

Subtask 2: Testing ticket DEF

Subtask 3: Testing ticket GHI

Another Project ticket : "This is a Project" and Subtasks under the Project

Subtask 1: T123

Subtask 2: T456

Subtask 3: T789

Now I want to create a Filter where: Project summary contains JIRA and it`s Subtasks summary is starting from Testing.

Thanks for the help.
