best way to manage 20 remote clients through SEPM

I've been trying to find a good way for an office that is halfway around the word to get policies and updates without directly coming back to the SEPM console we have here. I've been going through the documentation but it was a little unclear as to whether this is what the GUP is for. 

Can I create a group of servers within the SEPM console and then apply a specific GUP that is within their site so that the communication from the remote site back to the SEPM will be minimal? Is there a better way to achieve the update of policies and virus definitions? 

Thanks.
