Categories tree structure UI with brands and setting value with inheritance

Let we have a tree of categories as first column and commission as a second column. Commission has inheritance abilities, e.g. if I set commission on Category 1 by default it will be applied to Category 2

We can set commission also to brands for different categories, simplest example:

Currently it duplicates category row, but with brand label.

If we set brand commission on parent category it should be inherited by subcategories. In current UI it will duplicate a subtree:

How to display it without duplication of subtrees of categories?
