Marker or Home? There's a difference. Home stays put, Marker goes away on Close.
Another way is to set up a placefile. Then you can use a different Icon if you wish.

Now that I think about it, I'm not sure you can use Home twice. It may only work in the first (primary) instance and not in subsequent instances. Try it and see what happens. Or, it may only stay in whichever instance is closed last.
