Cascading Progress as a Metric Option

I use Griply in OKR format for personal goals: annual goals broken into half-year and quarterly goals, with measurable subgoals cascading beneath them.

I'd love to see a new "Measure Progress" option called something like Cascading Progress (or Weighted Subgoal Progress) that automatically calculates a parent goal's completion percentage as a weighted average of all its subgoals' current progress percentages.

Here's the gap I'm running into with the current options:

• Subgoal Progress counts a subgoal as complete only when it hits 100% — so if I have 4 subgoals each at 85%, my parent goal shows 0% complete, even though I'm nearly there across the board.

• Completed Tasks has a similar binary issue for task-based tracking.

What I'm hoping for: if 4 subgoals are at 85%, 80%, 75%, and 100%, the parent goal would automatically reflect ~85% progress — without me having to manually update it.

This would be especially useful for anyone using OKR-style goal structures where progress is continuous and gradual, not binary. I think it would also align naturally with how Griply already visualizes progress through its percentage rings and trend charts.
