Set maxlength/minlength dynamically?


Is there a way to set dynamically the maxlength/minlength option of a textarea field in a blueprint?

I would like the admin user to be able to choose the maximum/minimum number of allowed characters in a textarea.

The admin user enter a number manually in a number field for instance and i would like to fetch this value to populate the maxlength/minlength option from another field (textarea)

Doesn’t look as if you can use query language for these validators.
