How to auto-template nested resources in MODX REVO?

Question

CMS

How, using the "CUSTOMIZE FORMS" option, to automatically assign a template to your parent, your children, and your children's children?
For parents made according to this instruction https://www.youtube.com/watch?v=PS4TmQcohsA
it's easy. But it doesn't work any further.
Structure
PARENT - id 2
-PARENT1 - own template ok (with bounding field parent and value 2)
-CHILD1 - own template it turns out :(
-CHILD 2- own template turns out :(
-PARENT2 - own template ok (with bounding field parent and value 2)
-PARENT3 - own template ok (with bounding field parent and value 2)
How to deal with this?

You can use the Collections add-on. Among other useful functionality there is an option "Default children's template"
