Minimum number of characters/words

Is there any way in a "Paragraph text" field to instead of checking for a max number of characters flips it to check for a minimum number of characters.

I'd probably just need the original function code and some overload it to do a greater than instead of s less than. But I'd need help with this.

Many thanks

Word on the street is GravityWiz is developing a "perk" for this if you want to reach out and inquire.
