Use future shift rota data to calculate future shift statistics (recalculate for future time periods)

We have a future data tag for each shift team specifying, on each day over the next few months, whether they are on the day shift, the night shift or off-shift. I have an analysis that counts the number of days in the 'current' month that the team is on-shift (day or night).

I can recalculate that analysis up to today but it won't let me specify any dates in the future. But there's no reason this particular analysis would fail or give an incorrect result so is there any way to work around this and let me populate those future statistics?
