Ability to use band hierarchy with the docx-template

[NikitaShchienko]

I want to use nested bands (as nested tables) for DOCX files in Reporting Engine.
For example, I have Services->Assets->Items and I want to get the next result:

Patrol
Asset 1
– Job 1
– Job 2
Unlock
Asset 2
– Job 3
– Job 4

But it doesn't work correctly.
