Importance of each item in MaxDiff TURF?

Hi,

We're using the MaxDiff Analyzer in order to perform a TURF Analysis on a MaxDiff survey - each method used is "Weighted by probability".

After receiving the optimal reach portfolio, we'd like to know how much form the reach is explained by each item (a Shapley value TURF if you will).

Is there a way to do this?

Alternatively, is there a way to transform the probability of choice / utility matrix from decimals into dichotomics (i.e. 0 / 1)? We would be able to determine Shapley values using external software in that case.
