Hi,
use object-group to create objects,
And to group them use
object-group
)#group-object
e.g. i am having to web servers, so i will create
object-group network WEB_SRV_1
)# network-object host 10.10.10.10
)#exit
object-group network WEB_SRV_2
)# network-object host 10.10.10.11
)#exit
object-group network WEB_SRV_GRP
)# group-object WEB_SRV_1
)# group-object WEB_SRV_2
)#exit
In this way if i have to apply any rule particular for webservers then i can use WEB_SRV_1 or _2
If i have to apply rule to all web servers than i can use WEB_SRV_GRP.
You can easily add webservers to group. Instead of network as type of object you can use service, then you can mention serrvices like tcp ,UDP port number etc
Cheers
