When you create a Report Extension you can modify existing fields on the Request Page of the report, changing captions and behavior of those fields but you cannot change the caption on the report or on the request page.
We would like the Caption of the Report and the Request Page to be accessible through the Report Extension object the same way as it is in a Page Extension object.
Additional context
When extending the functionality of an existing report we would like to be able to reflect this in the Caption.
E.g. if the existing Request Page caption says "Create Sales Invoice" but we extended the report, adding the ability to create Sales Order, we would like to be able to change the Request Page caption to "Create Sales Document".
However, in the current setup we cannot just extend the existing report; we will have to copy the entire standard report to a new object and modify it to get this result.

Thank you for this suggestion! Currently this is not on our roadmap. We are tracking this idea and if it gathers more votes and comments we will consider it in the future. Best regards, Business Central Team
