single reference screenshot for multiple/same elements

Hi @garris ,
I've a reference screenshot for an HTML component (0_0_buttonclass_0_desktop.png) that i need to match against multiple components (buttons on the same page) that have the same CSS class names. For now, only the very first component is getting matched and others are ignored.

I don't want to duplicate the reference screenshot as the expectation of other button components are going to be same. But i want to test it to make sure they are same.

Do we have any provision for this one?
