Graph selecting in template

Hello
We use
grafana-4.3.2
influxdb-1.2.4

We try to replace our munin for grafana
We make template for host where we can see all graphs per host

but we want see complex data by all host and specific graphs. For example select all hosts from group and graph only disk space using repeat panel by hostname:

How we can filter displayed graphs on template? Or we must make template per all needed data (Disk space,cpu, etc?)

take a look at this demo dashboard that shows of some of the templating features:
