Ability to rename "Megarow content"

Problem/Motivation

Create a new view
Select the "Megarow table" format
Add a "Megarow links" field
In this field enter one megarow link per line, the structure of a link is the link title and its path joined with a pipe sign (|) (eg: Preview|node/1).
Save your view and display your table
When you will click on a link, Drupal will load what's behind this page and will render it as the <strong><em>megarow content</em></strong> below the current result of the view.

Is it possible to add config to rename "megarow content" which is displayed once you click on "Preview" from above case ? This title can be confusing for users.
There is option to Rename "Loading" or Close button "X" so I believe this Title can be added there as optional also...
