MS Project Online - Customize email reminders & notifications messages

We need to have the availability to customize the info that project online alerts and notifications send at user level. Can we have this option?

The problem appeared in the case we have project with subprojects, that have common name of tasks.

In that case the email, send notification with the task but not for which subproject. In practice this is a big problem. Any idea to handle the problem is appreciated a lot!
