Specify hybrid values for expressions in CFX-Post?

When creating expressions in CFX-Post, is it possible to force a hybrid calculation?
This question stems from my desire to calculate an average Nusselt number on the top surface of the outlet of a rectangular channel. To obtain the average heat flux I am using the following expression:
lengthAve(Wall Heat Flux)@TopLineOut
Here's the problem...

Hybrid/conservative value thing does not apply to surface integrals on boundary faces, but you are trying to do a line integral I assume on a boundary face. What I would consider doing is to replace your line integral with a surface integral where the surface you are integrating over is thin, so it is just about a line anyway. Then you evaluate the area integral and that should work fine.

in CFX post go to:
Calculations ==> Function Calculator
then set your request. For example lengthAve(Wall Heat Flux)@TopLineOut
then at the bottom of Function Calculator tab, Press Hybrid button.
after this CFD Post automatically uses Hybrid Values For your Expression
