Funnel chart: Count following groups to current group

[XiangRongLin]

From trying around it seems that dimension describes the stages in the funnel and with metric i determine how big each stage is. With these options I can't seem to display my usecase

Given stage order A -> B -> C then I want that all entries in stage C are counted towards the stage B and the same for B towards A. But with it currently displays how many are currently in the stage instead of how many were once in the stage.

Is there some way to display my described behaviour
