Powerscale Ansible isi zone zones modify --add-user-mapping-rules=

Hi,

I'm looking to do mimic the command:

isi zone zones modify --add-user-mapping-rules=

Is this something I should be able to do?  I don't see a matching parameter and hoping I'm missing something.

If not, can you please point me to the API call that will do this.
thanks.
glenn.
