Customizing split screen by specifying the ratio between the heights of the splitted apps?

[Zoltán Bíró]

Is there a trick in Tasker to customize the split screen layout by specifying the ratio between the heights of splitted apps (or widths in lanscape mode)? 

E.g., one might want a bigger windows for the upper app and a smaller one for the lower app. Most of Android implementations allows this.
