Is it possible to get the average of line support results?

By means of the "Show" Navigator the different possibilities can be controlled.

Under the "Results" category, you can switch between "Actual" and "Smooth distribution" for the storage reactions. Again, the variants "Constant (average)" and "Linear" are available for selection (see Figure 1).

Incidentally, a smooth line can also be displayed when displaying the result diagrams (see Figure 2).
