Feature request: Change bg-data to something else?

Regarding Lazy load background images. I was wondering if it would be possible to modify or add a new path to the background image? I am using BeaverBuilder to create some of my pages and they use their own inline style attribute called:

<div data-parallax-image=”/path/to/image.png”>…</div>” for parallax background images.

So in essence, I am asking if it would be possible to change the hook from Lazy Load XT somehow? That would be awesome as all my background images are currently loading when the page is loading.

Best regards,
Michael
