How to find mean temperature over area or volume from PDE solution?

I am using the PDE toolbox for a steady-state thermal analysis. The solver provides the temperature at each node and I can use evaluateHeatRate to get the heat flux through a face but I cannot find a way of getting the area- or volume-weighted mean temperature through the body. Is there a function that does this (rather than simply averaging the nodal values with no weighting function)?
(My body has 3 temperature boundaries. I want to solve using 2 independent temperature vectors, get the mean temperature for each and then define the body-mean temperature as Tbar = a*T1 + b*T2 + c*T3 so I can evaluate the pseudo-steady heat capacities dU/dT1, dU/dT2 etc).
Thanks
Roger
