Number Grandchildren

I use Dynalist for screenplay development. We work with Acts and Sequences.
In a screenplay, scene numbers continue across these acts and sequences.
In Dynalist, when we tick ā€œnumber childrenā€, the numbering restarts for each of the siblings.
With a feature ā€œnumber grandchildrenā€, numbering would continue across the children, and each grandchild would receive a unique number. Like this:

Act 1
Sequence 1
Scene 1
Scene 2
Scene 3
Sequence 2
Scene 4
Scene 5
Scene 6
Act 2
Sequence 3
Scene 7
Scene 8

I hope fellow writers see the benefit in this feature!
