I don't see a way to do it this way. What you want is "move to X/Y position" as this option is "grayed out".
What can be done:
- Add an "open" action button to you main window in the correct position.
- Add a pop-up window
- Add a "close" action button to the pop-up window
- You can replace the "open & close" button with a matching graphic
- Align all items for seamless display.
Not exactly what you wanted, but at least only one pop-up window.
