Nesuss Excluding list of IP from scan

Recently I found that I need to exclude some IPs from scan.
As I did it in windows :

In the c:\ProgramData\Tenable\Nessus\conf\nessusd.rules


# Target Syntax: accept|reject address/netmask:port[-port_max]
#
# Reject any target on 10.42.***
 reject 65.132.***
 reject 50.233.***
 reject 96.93.***
 reject 216.174.***

As this IPs were in the different places subnets, i used this way. May be there is different and better way.
