Is it possible to embed on a button's label an icon

Hi all,
I got a couple of button on a grid header and I would like to add a little image/icon of a cart just in front of Label button text.

IconImage {label button text}

I don’t want to use Display Mode --> Image becouse I got a theme and I don’t want to have something on grid with a different style.

The icon is attached (Use a magnifier… to see it ;-))
