Change 'New Message' title in Push Notification for mobile phones

When user performs some actions in the app, the user receives a Push Notification.
If the app is closed and a new Push Notification arrives, this message is shown in the mobile notifications. Now all JA notifications have the standard ‘New message’ title.
Is it possible to change this title for each individual notification?

At the time of writing this, the title is not changeable. If you would like to see this feature in future releases of the JourneyApps platform, please submit an idea on our product roadmap.
