Use Sketch Router instead.
The behavior of the autofinish function can not be configured?
I don't know, I use Sketch router ... more efficient and quicker.
Sketch router won't add vias. Only works on active layer.

Not sure if this also works in pads professional but in expedition PCB there is another auto finish method using the alt key that doesn't add vias:
- Hold the alt key during the multi-plow command
- Move your mouse to control the autofinish routing
- LMB click to complete the autofinish routing

The reason that autofinish gives you the vias is due to the bias of the layers.
IF you will check you will notice that the blue layer has a horizontal bias, the red one a vertical bias.
Autofinish (as well as autoroute) will honor the bias and follow the layer that has the biased direction.
Sketch router will not honor bias, but will keep all on the same layer as the starting point of the trace.
Hope this explains it.
Thanks, your advice helped.
