Android for Work: Add --user variable

Running a APP on Android Device from Qt Creator always runs the APP for User 0 - the first private User.
Deploying the APP to a managed Android Device the APP should run using the work User (typically User 10)
It seems that Qt always starts the APP without --user argument which means the default User (Id 0) is used.
List of users:

adb shell pm list users

starting the APP with --user would look like

adb shell am start --user 10 -n my.app.package/org.qtproject.qt5.android.bindings.QtActivity

My workaround at the moment:
Added External Tool with .sh Script killing running APP for user 0, then start APP user 10
Now I can use the unmodified Build + Run, then execute External Tool to kill the running app and to start with correct User.

Would be much better to add a variable USER_ID to be placed inside .pro and - if exists - start the APP with the given user ID.
This would also help if an APP should run for another private user (id 1...9)
