Mass user creation at HANA

Hi

we need to create mass user creation in hana.

we have user A as template. and need to create more number of users(say 40users) at once.

hope this can be done in SQL command right?
do we have option to copy the roles and user info from User A to User B,C,D etc

for eg, for one user and one role below is ok.
but for many user and many roles to be added. how to achieve this.

CREATE USER my_user PASSWORD My_Password;
GRANT MODELING TO my_user;

Regards

Chandra
