Idea for a trait addition: VnV Overview

[Jabberdau]

When I played RTW and was going to select from 5 - 6 different family members to select one for governor, it always was a tedious process to note down on paper what bonuses to trade, squalor and law each member had as these "traits" was not included with command, influence and loyalty.

Question:
Is it possible to add a trait that occurs on all family members that summaries the trade, law and squalor bonuses/negatives for MTW2?
If a family member has 2 traits fx, one that gives +20% to trade and a ancillary that gives -10% this trait would then change accordingly to provide the number "+10% Trade" when hovering the mouse over the "VnV overview" trait.

I don´t have MTW2 yet, so I am just watching from the sideline for now, don´t know anything about modding.
