Have you considered setting more meetings with various stakeholders to discuss how to prioritize time for the next 2 weeks? And then follow up check in meetings every 2 days to change direction in an agile way?
(yes this happened to me before)
I do not miss development.
All the work to actually reach requisite agreement for the decision is done in the days / weeks leading up to the meeting via ad-hoc-ish one-on-one or one-on-very-few meetings (possibly including graft and corruption).
The "decision" meeting isn't organised until the result is known and guaranteed.
This maybe doesn't apply to Agile / Development-related meetings, but I'll keep trying to determine how to make it apply, such is my disdain for this (seemingly) waste of the team's time (he said, whilst posting on HN).
