Not with the plugin itself. You will need to look into CSS / JS solutions for this online.
You could try the following JavaScript, which would need to be added to your theme or as a separate plugin:
jQuery( document ).ready(function() {
jQuery(".ccchildpages").each(function (){
var maxHeight = 0;
// Equalise child page containers
jQuery(".ccchildpage", this).each(function (){
if ( jQuery(this).height() > maxHeight ) {
maxHeight = jQuery(this).height();
}
});
jQuery(".ccchildpage", this).height(maxHeight);
});
});
