I work the same way and having a keyboard shortcut set for each one of my Apps has been game changing for me. Worth trying out to see if it fits your flow:
KDE's window manager, Kwin, supports this functionality built it.
Just right click on any title bar on a window, go to "Special Application Settings" -> "Arrangement and access" -> "Shortcut". You can manually type "F8" in the shortcut and it'll work just fine.
You can also go to "System Settings" -> "Window Rules" to manage all rules you've defined.

EDIT: Turns out it's trivial, I love Linux:
