I want AI to re-work my estimate items to match exact grand totals or exact section totals.

I like the itemization the AI does. Sometimes though, I have a final price already established for the project or for a section. This may be because I have a price expectation set with the homeowner, or because I got a sub bid for a certain price, or because I just want to round-off the estimate total a certain way. I want to do this while editing the estimate, not the proposal.
