B4J Question Designer Scrool Problem

Hello everyone
I need to show in my application a very long form with many different views (combobox, textarea, tableview, ...)
My idea is to show it on a ScroolPane.
The Layout that I have created is about 4000 pix in height.
In the Designer I have created a variant of 4000 pix in height, but my problem is to move to the lower part of the layout without having to reduce the zoom level.

Any idea?

Thanks in advance
