If you cut end area volumes at odd stations in this manner it would mess up the computations of the EAV results. This is because we would have to compute a ratio of difference between the cut section and the station you specify and this is not a valid process in engineering for the End Area Volumes computations.
As a workflow, you should include the cross sections you wish to include in the limits when cutting the cross sections. Then they can be used in the End Area Volumes. To do this you have to use the Custom cross sections and add the station range for the normal interval and also add the perpendicular stations at the specified stations you want to include in the limits. They have to all be in the same cross section set in the model, which is why you wouldn't get results just from copying the graphics from a new set or a new section you generate. They need that link.
