Not sure about V. 25 but I could not locate a specific report format in V.24 of the final that will show the percentages. Since it sounds like this is a request specific to that client, I would suggest doing something like putting the percentage in ( ) up on the description line at the end and explaining in your captioned report what you are doing. You will only be doing it on depreciable items anyway and not necessrily on every one.
The only other option I could think of would be to add a single attachment at the end of each room where you might say ... The depreciation applicable to each trade shown above is as follows: Drywall - 25%, painting - 50%, finish carpentry- 15%, etc. You could cut and paste that for the most part if the levels all stay the same.
I would think that the later versions have that as an option. Guess I am going to have to final upgrade my edition.
Good luck and let us know if you find out a different possibility.
