onlyOnPreview() Filter / Rule

[ibrainventures]

Sometimes we render Image Quality only in the Preview Modal.
There is this filter / rule missing.

Would be great to get this rule inside the offical Release.

    /**
     * Specify that the element should only be shown on the preview view.
     *
     * @return $this
     */
    public function onlyOnPreview()
    {
        $this->showOnIndex = false;
        $this->showOnDetail = false;
        $this->showOnCreation = false;
        $this->showOnUpdate = false;

        return $this;
    }
