Default watchers per reporter

Our JIRA users are requesting a feature that would automatically add a pre-defined list of people as watchers to each issue they create. Specifically, their manager has requested to be a watcher for each issue they create.

Example
When user-a creates an issue, they want manager-a to automatically be a watcher.
When user-b creates an issue, they want manager-b and manager-c to automatically be watchers.

This could either be configured...

...through the profile of user-a, saying that they want manager-a to be a watcher on all issue they create in any project.

and/or

...through the profile of manager-a, with a special permission, saying that they want to be a watcher on all issues created by user-a in any project.
