METRIC-rpt: How do I get one graph per selected host in same page - Not combined

I have a graph with 4 data elements, (CPU utilization ), and I want to gen a monthly report graphs, one each host, one page for customer.
Metrics works great to get one graph per host, per page. multi-host always attempts to combines data into one graph.

I've seen.. "just add comma hostname in the URL"  which doesn't work for me for some reason.
Is there a way another way to do this, what am I missing on this add comma hostname advice?
