How can Jira automation rules be editable for project admin

[Jira]

I have created a jira automation rule for a single project and have the admin access to that project I am able to edit the rule.

However when the rule is extended to another project where I am also an admin, I am unable to edit the rule.

To edit the rule to the scope as multiple projects jira administrator access is required.

Any suggestion why is the roles defined in such a way to not allow projects admin managing the rules and are any ways to edit the rules without Jira admin access?

There is no outofthebox functionality for that case. 

But it can be achieved with plugins like Adaptivist Scriprunner

for example:

It's similar to you case.

In your case you'll need to do custom post-functions on all subtasks workflows, that will check all subtasks and if they resolved add comment to parent issue
