missing domain mapping option in tools wp-admin panel

Hi I have a new domain and install at wp-engine as a host. I believe I have sunrise installed and working properly but in my first multi-site off the main site the domain mapping option is not in the tools menu.

It would be nice to have someone login through the control panel and just confirm I've set this up properly. It's early in the install - a good time to get it straight.

I've already granted support access.

Thank you!
