AVERAGE of YES/NO Values

Hi Devs,
I have some data elements that are of type YES/NO for example, in the attached screen shot the “EPRU -Pre-Plan Approved EPP in Place” is of yes/no type with the aggregation operator set as average (yes/no). It only has one value set to true/yes in the system. I have seen this post here -http://osdir.com/ml/dhis2-devs/2012-02/msg00346.html with the explanation regarding this issue. However is it possible to have

i) Average operator that does not convert the values to (%) , this is important when creating indicators since one has to keep dividing yes/no values by 100.

ii) Display (%) sign in the Pivot Table so that users can be able to see that the average value has been converted to a percentage
