How to get a extra icon on a shape when a hyperlink is set on that shape

[Cromme123]

When a hyperlink is set on a shape and I hover over that shape the mouse icon changes.
I want to export my flowcharts to web pages. Than during hovering over the shape the mouse icon will change to a "hand" on all shapes, also on those who doesn't have a hyperlink.

I was thinking about getting an extra icon with the shape whenever there is a hyperlink comming with that shape.

How could I achieve this?

Thanks in advance.
