Row attributes / div attributes

Hello.
I really love row attributes function in site builder like adding custom class / css for whole div but i found it insufficient. For example if i want to use jquery plugin like wow.js adding:

<div class="wow slideInLeft">

to row there’s no problem. But what if i also want to configure it adding:

<div class="wow slideInLeft" data-wow-duration="2s" data-wow-delay="5s">

Basiclly what’s missing is another input box for adding no-class div attributes like in this example data-wow-delay=”” and such. Can this be somehow done ?
