Not sure if this is already a function for multiple monitors - description . . . here goes
WIN KEY + E produces a window, WIN KEY + E produces a second window in the same monitor.
I know it is an absolute nothing function but could a repeat window request produce a window within the next screen, as I or most people only open two screens to drag and drop across.
I know this is laziness to the extreme but it would also look good to anybody behind you as you tab up two screens via hotkeys!
I was able to put a scripted function together that should do what you need. To use it, you will need to set up a trigger with the newest DisplayFusion beta. Here's how to set it up:
Open the Triggers tab in the Settings window
Click the 'Add' button to open the Edit Trigger window
Set the 'Process Filename' to the Windows Explorer application
Set the 'Window Class' to "CabinetWClass"
Add a 'Run Function' action to the actions list, that runs the script I have attached to this post
I have also attached a picture of what your trigger window should look like when everything is set up correctly.
