Warning text when exceeding the text limit in Essay question

Hi E-Learning heroes,

I've created a slide with an essay question, I've set the maximum number of characters as 500.

Is it possible to show a short warning text when learners' entry exceed the limit? For example, "only 500 characters allowed" in red.

Currently the text entry stops automatically at 500, but nothing shows as hint for this stop so it might cause confusion to the learner.
