Pushpins properties

When I insert a pushpin manually or importing a file, these ones doesn´t works like the ones that represents the restorants, hotels, etc..
I mean that the last ones appears from a certain zoom level like little squares, then if me make zoom + the image appears with the complete icons picture. This doesn´t happent with the pushpins that I`ve inserted, they always appears with the same size in any zoom level, so when I have a little zoom level the map is full of icoms and these is a completed mess.
Anyone knows if its possible to have the same properties on our references as in the Mappoint references?
Thanks.

P.D.: Excuse my english!!

I have not tried it myself but I don't see any reason why you could not change a pushpin based on Altitude. You could have a custom pushpin that is smaller for when you zoom out. Changing the pushpin for a dataset is not hard to do.

What means change the pushpinn for dataset?
I,ve just want my personal pushpins having the same zoom properties like the ones which mappoint uses to represents restorants, etc.

I'm sorry, I assumed you were programming. using MapPoint interactively without some custom programming it would not be possible.
