I think the "correct" approach here is to move the calc from the DM step to an actual calc defined within the WF, if I can actually get it to do what I need.
Of all the weird things I've done in OS over the years, it's probably bizarre that I have literally never used this screen before.
The DM calc is just a consolidation of the full year but it appears the time for a WF calc is always just the period. This may be why they used the DM calc instead. Is there a way to have it consolidate the WF year instead of the period?
