I recalled in the time when I use R75 there has a function in group object.
when later the user adding a new Host/network object with the pattern of the name then it will ask you if you like to add that in a specific group. but I cannot found on smart console / google. is that just something the name changed or something I remember wrongly?
group-webproxies created, it will match the keyword "proxy"
when later user create host object abc-proxy, then it will ask if we want to put an object into "group-webproxies"
