It would be helpful for the custom reports to link the deal name property (when used) to the deal. This currently is how it works for standard reports, just not the custom ones built from scratch. This is also the same use case for tickets.
Linking to the deal/ticket, is more efficient if needing to update or close the deal/ticket information.
E.g: I am creating a report to show all stalled deals/tickets in a stage, it would be helpful for us to then click into the deals/tickets we want to investigate or update etc.
