Shortcode different icon

Yes,

This is a feature of Print-Pro-Matic, but it can be done with the free version by manually overwriting the default CSS. The current CSS for the default icon is as follows:

.pom-default {
	background-image: url('print-icon.png');
   	background-repeat: no-repeat;
	width: 32px;
	height: 32px;
}
