calculatePartial on MultiTargetPaths

We are using MultiTargetPaths for some of our Pathfinding. MultiTargetPaths inherit the bool calculatePartial from ABPaths but does not seem to implement it. Looking at the documentation this seems to be Work in Progrees.

Is there any workaround to make MultiTargetPaths not choose partial Paths?
