Summary:

Is it possible to change the prompt in redwood pages through VBS, earlier it was possible only through sandbox search text tool(which is difficult as it will apply to all the pages).

In ADF we can create a sandbox with page composer tool and update the prompt for a particular field. But in Redwood page through VBS we are not getting option to change the prompt for a particular field. I understood it is possible through Sandbox , User Interface Tool, but it is very difficult to make sure where are the change going to be just by looking at the search results.
