Is it possible to add a filter for unsupported value columns?

[andruxnet]

I have a custom ACF field that represents a MongoDB object. In the Admin Columns UI I can add the column for this field, but it renders as "Unsupported value format". I was looking for a hook that would let me manipulate this $value before it being rendered (like grabbing a Mongo object property), but couldn't find a way.

It would be very helpful if the Unsupported column class would filter the value before returning.. something like this:

class Unsupported extends Column {

	public function get_value( $id ) {
		$value = get_field( $this->get_meta_key(), $id );

		// new filter to try and parse the unsupported value before giving up with the "unsupported format" message
		$value = apply_filters( 'ac/column/unsupported_value', $value, $id, $this );

		return is_scalar( $value ) ? (string) $value : __( 'Unsupported value format', 'codepress-admin-columns' );
	}

...

}

Then, we could use it like this:

  add_filter( 'ac/column/unsupported_value', function( $value, $id, $column ) {
    if ($value instanceof \MongoDB\Model\BSONDocument) {
      return $value->title;
    }

    return $value;
  }, 10, 3 );

Any chance this change is included in the plugin?

Thanks.
