How to tell Move/Resize which screen to choose if window is getting moved where there are two screen choices?

I'll precise my question a little bit. I currently have this screen layout

and would like to be able to move windows that are on the screen to the right on one of the two screens on the left. However, even with this configuration, it seems BTT is unable to decide which screen the window will go to, as it has two choices.

Are there any ways I could force the window on the right screen to go on the top left screen, for example?
