In the display, there is nice box labeled EXTENSIONS and then each of the extension buttons is below. I want to group the extensions into 3 piles (groups). I noticed that if I enable my user (say 500) to include 3 groups, all the extensions in those groups are sorted together into one pile, labeled EXTENSIONS. How can I set it up so that I see 3 groups, such as MEENY, MINEY, MOE. It seems that if you go multi-tenant it does break them into piles, but by creating multiple event streams coming in that will slow the system down considerably.
