Auto discovery with a template

[ascssmith]

ok, it says:

Manage Templates

Manages template files used for automatic discovery. Automatic discovery can use these templates as input to the IP address inclusion range. The template should contain range selections like those used in the automatic discovery IP inclusion ranges.

BUT, whenever i use a template, it wants an ip inclusion range ?

i have (108) locations on different subnets, so that's why am trying to use a template with all their ranges in it, instead of each one, ex:
172.16.101.1-172.16.101.254

can someone tell me what i am doing wrong, in order for the auto discovery to use my template, in staead of:
172.16.101.1-172.16.242.254, which cover way too many ip ranges and takes forever...

thanks
