Hi Petr, under the current setup that won't work because that dialog is not static - when you open it up the values in it will reflect the current 3D view orientation, not just the last values that were entered there.

In fact, you can rotate your view around when the dialog is showing and the values will dynamically update to the current view orientation.

So the dialog itself does not maintain some different setting from the view, it's more of a reflection of the view so you can both see and edit the view angles there...
