TSM Accounts

Good day Friends,

I have a permission issue TSM users:

I have a total of 7 analysts working with TSM perform the same basic tasks such as tape mount, removed the tape for the safe.
Every analyst has their user with privileges and STORAGE OPERATOR.

But an analyst working on shift at night need to cancel some migrations processes that are running and generating competition drivers and only the SYSTEM cancels these processes.

My question: Has modifying the OPERATOR / STORAGE privilege to cancel processes MIGRATION, or just the SYSTEM have this privilege?

I thank you.
