Bitrix. How to implement such a structure?

Question

1C-Bitrix

Hello.
There is a structure - 2-6*direction->3*section->10*element->element page
Conditions:
1 direction = 1 page
Sections are the same
The element page template from section 1 differs from the element page template from sections 2 and 3. (t .e. only 3 templates)
The element page template is complex - there are many properties.
The content designer should easily create an element page in the section and direction he
needs. It is desirable, but not necessary - the content developer should create directions.
Please tell me the best way to solve this problem
