Is it possible to add reverse= to position_dodge()?

[datafj]

Currently position_stack() has the reverse parameter to change the order of stacking, but this feature is not available in position_dodge().

One would need to reverse the order of dodging in a group bar chart when it is a horizontal bar chart with the vertical axis starts from the top to the bottom.

@karawoo maybe this would be worthwhile to add once you've finished this round of dodge changes?

Yeah, I think that everything is set up to handle this already and it'll just be a matter of adding the argument to position_dodge() and position_boxdodge().
