TextArea or Input Component event handling inside a labelling task

Hi label studio team, I have a question… Is there a way to do custom validation on OnBlur event or OnChange maybe inside a TextArea or Input Component? We need it during a Labelling task where we need to check user input to avoid text containing errors or useless spacing or any others kind of check to avoid malformed data.

It would be also useful to have a way to display a contextual input error message.

Thnx in advance, for your awesome work.
