runtime averaging along homogenous directions

I am simulating DNS of channel flow where the x and y direction have periodic BC. I want to compute a profile in z (the non-homogenous direction) of the fluctuating velocity components. To do this I need to average the velocity components at each z=constant level of my structured mesh.
I have searched the OpenFOAM literature and forums and found only approximate solutions. I could use a sampling function object but my problem is how to specify that, at each time step, the function object must sample at several planes along the z direction?

In this thread a sample utility is presented
where a plane is obtained by averaging in one direction.
But, if you only want to have a profile (i.e. a line), you should use this application:
If there is any possibility to do this during the runtime, I have no idea, but I would like to know
I hope it was helpful!
