Disabling Paste Function

I am in need of urgent help with this project. Have you ever worked with 300+ page documents and want to run a blackline program on them, but because someone pasted something “hideous” in the document, you are unable to compare 2 versions of the same document or even compare it to another document? Well, I find that I am faced with this issue daily at my place of employment.

Can anyone tell me how to disable the Paste function and/or write a macro that would only open the “Paste Special” option when the user tries to paste text in Word? I would like to try and force this option, as explaining the problems this causes in documents does not work.

I am looking for an answer real fast

Thanks all.
