This feature is needed on Polystats projects that we are starting on stats.stackexchange.com. See these threads for what they are: What should be our first Polystats project? and How about starting a Polystats Project?.
By design, the questions related to Polystats projects are more about housekeeping to ensure that the project moves from one phase to the next. Thus, marking them as CW makes a lot of sense. However, we need to encourage users to provide good answers especially in the later phases of the project. Thus, awarding rep for answers makes sense.
In any case, irrespective of whether this feature is implemented or not, is there a workaround to achieve the above?
