Select which disk to graph for diskio graph

Hi

We have few linux physical server with more than 100 disks.
The problem is when I want to see the rrd graph for the diskIO part. As it prints the rdd graph for all disks, it takes long long time to do this, the interface is not userfriendly in this case.

Should be nice if you could select which rrd graph we want to see for the diskIO part…
