Create unique user profiles for each separate session

Hi,

How can I configure TS environment so that each user (who logs onto Windows using the same generic Windows user ID) gets their own unique Windows user profile.

For example, imagine a scenario where the users are logging onto Windows using the shared user "SYSTEMAPP"

The intention is to configure the TS server's Windows, so that it creates unique user profiles for each separate session, for example:
- SYSTEMAPP
- SYSTEMAPP.000
- SYSTEMAPP.001
- SYSTEMAPP.002 (etc...)

The server version for TS is Windows Server 2012 and not joined to AD. User IDs are created at Local Users and Groups.

Kindly advise.
