Item Rule Validation Error when we cross the 30 Characters on Item Description character limit

Summary:

Content (required):

In our Business Requirement we are using the Item Rule Validation on Item Class to restrict the Item Description with 30 Characters only, It shouldn't exceed the 30 Character,

If user trying to update it with more than 30 Character we are getting error when we save the changes.

Can we get the error at the same moment when we exceed the Item Description after 30 Characters?? Not when we save the Item only.

We need error to show at the moment once user type 31st character in Item Description.
