Layout hierarchy - wish

Hello, on personnel project I sometimes have many plans that I what to organise, as the layers
Parent layout and child layout, as with layers, having the possibility to reduce list by clicking on arrow icon
And may be having some document user text inherit from Parent layout ( as title for example)
It will be useful when creating multiples layouts of different objects on the same project:
Layout General Object01 (Parent) (ex Layout name)
- Layout of details 01 (Child) (inherit parent Layout name into text field)
- Layout of details 02 (Child)
- Layout of details 03 (Child)

Thank you for your help
