How to rename performance document headings only for specific documents without affecting others?

Content

Hello,

I should rename some labels in performance document pages. However, if I use both page composer or user interface text tools, customization are automatically applied to all documents; while I need to rename labels only for specific documents.

Is there a way to make label customizations effective only for specific documents without affecting others (i.e Expression language)?

Please, see the attached screen with highlighted in red some labels I want to rename.

Thanks in advance for your time!

Kind Regards,

Valerio
