[Plugin: WordPress Menu Creator] Add Menu from a different page

I am working on a custom-themed site and am using WP Menu Creator for the menus. The work here section of the site is 3 levels deep. I do not want the 3rd level to show up in the menus anywhere.

I figured that part out.

https://www.enviromedia.com/beta/careers/

However, if you go to this page

https://www.enviromedia.com/beta/careers/internships/

The third level shows up with the 2nd level. I want the menu from the careers page to show up on all of the internship pages. I don’t want the internships listed on the intern pages. Does that make sense?

Thanks in advance,
Lisa
