using setScale function relative to a custom point

[Yunus]

I have an item and I am zooming to some specific regions of this item. Zoom In and Zoom out is achieved by setScale function().

the documentation says:

The item is scaled around its transform origin point, which by default is (0, 0). You can select a different transformation origin by calling setTransformOriginPoint().

So I don't want to zoom always relative to (0,0) point. however using setTransformOriginPoint() function changes the coordinates of elements belonging to my main item.

How can I zoom to a custom point without changing element coordinates inside ?
