How do you add more element fields to the Available Element Field list in CSV?

[mse]

In the CSV specification, under the Available Fields, you will see things like GUID, Phase, Priority, Author, Scope, etc. I would like to add to these fields. Where in EA can I do this?

I would like to avoid using the Add Tagged Value Field because I want the names of the columns in the resulting CSV file to be exactly what is shown in the Available Element Field. The Tagged Value Field for example always prefixes everything with "TaggedValue_"

That's just what's available. You can't add field that don't exist.

Everything you add using profiles are in fact tagged values (even though they are shown in the properties panel)
