Writer: Maximum character length in text form?

Our staff wrote a form in Microsoft Word that has character amount limits in various fields. One field cannot contain more than 200 characters. Another cannot contain more than 2,000. So different fields have different limits.

Unfortunately, those limits are not enforced when the .dot or .docx files are opened in LibreOffice 5.x, which the majority of our staff uses.

Is there a way to enable these character limits for pre-existing text fields from Word documents in Writer?
