What is the most efficient way to enable the SNC name for a large number of users ?

Dear all, I am getting ready to roll out Netweaver Single Sign On 2 for all my users. An important part of the process is setting up the SNC name for all users in all systems however this can take a huge amount of time if done manually through transaction SU01.

Is there a way to do it in bulk for multiple users at once ? What is the most efficient way to do this ?

Thanks in advance !
