Can we have multi level BOM for CTO?

Summary:

Multilevel BOM for CTO is possible or not as we can make multilevel structure in PIM but in Pricing we cannot expand that structure to assign price to item.

Content (required):

ATO model 1

Option class A

Option class 1

Option item 1

Option item 2

Option class 2

Option item 3

Option item 4

We are not able to see option class 1 and 2. Is option class under option class is valid?
