Find Names, Replace with Pseudonyms, and Create Table

I have already written my dissertation in Scrivener and now need to find all the names of my participants/subjects (i.e. characters if I were writing a novel) and replace them with pseudonyms. I also need to create a table/list of all the participants/subjects along with their age and where they are from. Any ideas on how to do this?

You can use the project wide Find and Replace commands to rename your participants, and the Format -> Table command to create the table. But Scrivener has no way to guess the names without your help: you’ll need to either refer to your notes or read through the file to find which names you used.
