Hi, I want to use Notification Function in UX.
I want a function that Member can mail to Manager.
There are a function can select recipients by module.
So, I tried to use it and make this List and module.
List: Manager List & Member List
| List | Manager | Member |
| | X | A |
| | | B |
| | Y | C |
Mail Module (from Member to Manager)
| Appliers To | LineItem | |
| Member | Manager | Uses-Manager |
| A | X | X.~.com |
| B | X | X.~.com |
But in this case, I have to chose Member List in Recipient context.(picture)

I think I have to make a module has Users in Applies to.
But Users has no properties and I can not use finditem function,
so I can not find the manager address.
| Mail Module | |
| Users | Manager |
| A.~.com | ✖ |
| B.~.com | ✖ |
| X.~.com | ✖ |
How can I solve this problem? (Input Manager List to Mail Module by hand is not answer)
Please tell me idea!
