It might be possible, we'll check into it

I was able to put a script together that should do what you need. It will work best as a trigger, which you will need the beta version of DisplayFusion for (currently DisplayFusion 8 beta 5). To set up a trigger, follow these steps:

• Make sure you have the latest beta version of DisplayFusion
• Open the Settings window to the 'Functions' tab, and click the 'Add Scripted' button
• Paste the code in the file attached to this post into the window that pops up
• Give the script a name and press 'OK' to save the script to your computer
• Browse to the 'Triggers' tab and click the 'Add' button
• Check the 'Process Filename' checkbox and put an asterisk (*) in the field
• Click the 'Add' dropdown button and select the 'Run Functions' option
• Select the function that you saved previously
• Click OK to save the changes, then OK or Apply in the Settings window to have your changes take effect

I've also attached an image of what the Edit Trigger window should look like when you're finished. If you would prefer not to install the beta, all you need to do is follow the first four steps, and assign the function a hotkey or a titlebar button.

I hope this works for you!
