Can reviewer question rating scales be increased or customized?

Is it possible to increase the rating scale for reviewer questions beyond the default range, for example to 1-20?

Dryfta does not currently allow adjusting the reviewer question rating scale beyond the default settings; specifically, it is not possible to set the scale to 1-20. You can customize it to a maximum of 10 points. 

Reviewer scales remain fixed and cannot be changed to a wider range.
