Changing Scriptwriting Mode to Standard Text Mode globally?

Is it possible to change an entire project, globally, to Standard Text Mode, when some documents are in Script Mode?

I have many dozens of script mode documents peppered throughout a huge project. I would like them all to be changed to Standard Text Mode. At the time I wasn’t aware of them sneaking their way into my document.

I have tried to Select All in the Outline, and to toggle the Format/Script Mode/Screenplay off, but it doesn’t effect the individual documents.

Thank you in advance for your learned answers!

There isn’t a way of doing this, as typically one would never really need to do so. You can use the hotkey for this, Cmd-8, which should speed up the process.
