Is there any way to force/override a shortcut in an app?

Configuration:

PathFinder App (an alternative Finder app)

  • Keyboard Trigger: /
  • Action: Cmd + Del

Expected behavior:

  • Moves selected file(s) to trash

Actual behavior:

  • Selection jumps to first item in folder (default PathFinder action for "/")

Additional comment:

  • Weird thing is that it worked for a few days then suddenly stopped working, without any updates to the app
