Custom Fields

No. You have been asking this question for years now. It’s in the ideas category in response to one of your earlier requests: Fixed asset summary. The fact that it is still there means it has not been implemented.

Just so you understand (and I think I’ve explained this before), reports are hard-coded presentations of data. No report allows custom fields. Realistically, the most you can probably hope for is a footer section like the P&L report has.
