How can I enbale sub-tasks for custom ticket types?

[Sia _Nastassia_ Sharasheuskaya]

I have a new project where I want to track QA specialised activities. I have created a number of new issue types - for example: Test Request. There are cases where more than 1 QA would be working on any given ticket. 

What I want to do is enable the ability to create sub-tasks under those new issue types or if that fails, I would like to use some of them as "Epic" like tickets that could have child tickets assigned to different QAs. 

I cannot manage to find where I can enable sub-tasks for specific issue types and/or change the hierarchy of the ticket and make the type "Epic" like.

Additionally, I have a company-managed project so that I could pull in tickets from other company-managed projects for visibility.

The only place where I could find hierarchy is here:  Issue type hierarchy. But I cannot seem to edit this or add more than Epic to be on that level 1. (I'm the system Administrator for Jira)

Can anyone help with either or both of the above?

@Sia _Nastassia_ Sharasheuskaya  - Regarding editing the issue type hierarchy

Your finding is correct that in company-managed projects, it's not possible to directly add more issue types at the Epic level (level 1) through the standard Jira interface.

This limitation is part of Jira's design for company-managed projects.

Hi @Sia _Nastassia_ Sharasheuskaya 

To track QA specialized activities with multiple assignees within your company-managed project setup, consider the following approach. Enable sub-tasks for custom issue types, such as "Test Request".

As a system administrator, you can achieve this by navigating to Administration > Issues, selecting Issue types > Sub-tasks, and creating a new sub-task issue type

Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards

Hi @Humashankar VJ thanks, I'm good to go the sub-task way but how do I enable the subtasks to be created, let's say under the "Test Request" ticket type? I have already created a custom sub-task ticket type, how do I attach it to the specific ticket type - "Test Request"

This is the ticket types that I have attached to my project:
