client disk graph differences

I don't know if any else had noticed this, but I just started experimenting with the hobbit client in 4.1.2. I've found that the Hobbit server generates the disk RRD graphs in seperate graphs of 4 filesystems each. Which is a behavior I'd like to use in some of my custom graphs, but I don't see how to set that.

But, on the server with the new Hobbit client, all of the filesystems are thrown into one big graph. With over 40 filesystems on this one server, the graph isn't too usefull.

Is there a setting somewhere to tell Hobbit to split up X rrd files into seperate graphs?
