Can we customize the Category Book DFF to display fields based on orgs - Requirement for SLA customi

Business is expecting P&L accounts for certain assets based on category (< or > a certain amount) be picked up from Categories setup rather than from book controls.

We are aware that we have to customize the SLA for this requirement. But, there is 1 more challenge here, few assets fall in > amt category and few in < amt category for a same book (TAX Book). Now, user wants accounting to happen differently for the 2 categories assets, even for same book.

Is it possible? I was looking in a way to include a check at category book setup by enabling the DFF segment, but it gets enabled for other OUs as well, which is not required. Please let me know is there any standard way of doing this.
