Longer weighted power

I am getting used to my new Tru Trainer rollers. Instead of the twin turbo fans of my 30 year old Performance rollers they have a flywheel in the middle drum. I use Favero Assioma PM pedals. The power feedback on the Performance rollers was very quick, whereas with the flywheel on the new rollers there is always a lag and considerable fluctuation in power readings.
Is there a way to have a weighted average that smooths out the fluctuations but not so long an average that it will make short intervals problematic? The settings on the Sufferfest screen have limited options.
