How to add user list as a sub-menu for one option in a cascading select custom field

Question

I've created a cascading select custom field with a few options and their sub-menus.  However, I'd like to add this option as well:

Individual , and its sub-menu would be the users in the project.

Is that possible?

Thanks in advance

You'll need to find or write a new field type to do that, Jira's cascading select is just two options, not users or projects.
