Problem to Solve

Currently, users are forced to use the predefined 5 level certainty scale (very low, low, medium, high, very high). However, some users might prefer to label these levels differently, or have a different number of levels. This is especially important, since some users prefer a scale with an even number of levels, as to avoid tending towards the middle one and instead being forced to decide between slightly above or below average.
Then we could also use for example Kent’s Words of Estimative Probability, which is a 6 level scale (Almost Certain, Probable, Chances About Even, Probably Not, Almost Certainly Not, Impossible).

Current Workaround

Somehow map your own scale to 5 levels.

Proposed Solution

Allow to define these terms as custom values, as well as have any amount of them.
