Issues choosing menu links.

Our site has 3 main menus for 3 main sections - Members & Professionals, Patients & Public and Main Landing Page.

When we try to choose a menu link say for a Read More button, it shows all 3 menus jumbled together in alpha order - it's impossible to tell which menu item belongs to which menu.

Is there any way to show which menu item belongs to which menu without having to save and test? This really makes doing links in SPPB time consuming and error prone.
