Sub breakdown of goal metric

So this is a very specific use case, but I believe maybe more options could be useful to other Griply users.

I’m currently studying the Shakespeare play Henry IV Part 1 & 2 which in total combines 38 scenes.

I’m reading the piece on scene at a day, so I set the goal’s objective to 38 scenes as show below:

Here’s the thing, It’d be great to be possible to have a more detailed breakdown.
So 38 scenes would show as the final target number but the details would display a more precise breakdown that would be of that effect:
Henry IV - Part 1

• Act 1

  • Scene 1

  • Scene 2

  • scene 3

• Act 2

  • Scene 1

  • Scene 2

  • Scene 3

• ….

Henry IV - Part 2

Same logic would continue on…

Perhaps no need to go that many level deep, but a more “detailed” roadmap ALSO in the progress tab as described would be useful. And I would imagine other projects might beneath from that added level of detail
