Launch/Attach without filetype association

[Franiac]

I am fairly new to NeoVim, but i think I get the main parts right. I played around with nvim-dap and made NodeJS debugging work. Then I tried some frontend stuff with Angular and very soon I stumbled upon the following thing:

My launch.json for VSCode look like this:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Chrome",
      "type": "chrome",
      "request": "attach",
      "port": 9222,
      "url": "http://localhost:4200/*",
      "webRoot": "${workspaceFolder}"
    }
  ]
}

While coding I always keep the Angular Dev Server and an instance of Chrome with --remote-debugging-port=9222 running. Whenever I need to debug something I just hit F5 and, no matter where I currently am in the source code, VSCode attaches to the already running debugger of Chrome and I can hit my breakpoints. That's really neat.

This workflow does not work with nvim-dap. Every configuration is associated with a filetype. Maybe I am still missing something or it's a skill issue of some sort, but wouldn't it be great if the above config could just be run with dap.attach() no matter what buffer/file is currently active?
