how to import list of networks to block certain ISPs

Question

Hi, 
 I need to block specific ISPs. Since I'm Maxmind premium subscriber I've a list of all networks of each ISP. 
 Since that are hundreds of Subnets for each ISP I need to import them somehow, but can't find any function to do that. 
 I only found IP list, when creating new host object. I would like to create new object ISPx with all IP Subnets. 
 
 Thanks

Michael, 
 you can create an IP host as subent and then add all the subnet that belongs to the same ISP to an IP Host Group. 
 Also you can use API to create several IP hosts at time. You can find API documentation on http://docs.sophos.com/nsg/sophos-firewall/v16050/Help/en-us/webhelp/onlinehelp/index.html#page/onlinehelp%2FAppendixGGuides.html%23
