customize lineMarker popup content

I created the LineMarkerInfo like this:

NavigationGutterIconBuilder<PsiElement> builder = NavigationGutterIconBuilder.create(Icons.WIRE).setTargets(aPsiElementList);
result.add(builder.createLineMarkerInfo(element.getXmlTag()));

In the popup it shows the tag name, file path. But I want to more other information.
Can I customize the popup somehow?

Thanks
