[Observium] average trend line to the aggregate storage graphs

Hi, is it possible to add an average trend line to the aggregate storage graphs? Similar to what is on the standard usage Graph.

We are looking for a way to do some simple and rough storage growth prediction for an number of volumes as an aggregate.

If this is something we could do natively with Observium that would be great but if anyone has done something similar with the RRDs and can share that would also be good.
