Bug Summary and Steps to Reproduce

there are source files .c, .cpp now i want to compile them using with gcc/g++ respectively and i have figured out that according to https://code.visualstudio.com/updates/v1_68#_tasks vscode is able to choose different tasks as default task based on different extend name. and i think the default task should be the value of variable ${defaultBuildTask} in launch.json but not really whether there is an convenient way to let launch.json pick the proper task?

Steps to Reproduce:

1. open a new workspace
2. create main1.c and main2.cpp
3. modify .vscode/launch.json and .vscode/tasks.json as following
4. now press ctrl+shift+B, the corresponding file will be compiled
5. but if click the button upper-right vscode asks me to choose the default build task and configuration files.

here is a workaround by change the keybinding : open keybindings.json(see https://code.visualstudio.com/docs/getstarted/keybindings#_advanced-customization) and add:

[
    {
  "key": "f5",
  "command": "runCommands",
  "args": {
    "commands": [
        "workbench.action.tasks.build",
        "workbench.action.debug.start"
    ]
  }
},
{
    "key": "f5",
    "command": "-workbench.action.debug.start",
    "when": "debuggersAvailable && debugState == 'inactive'"
},
]

if there is a direct way to work out plz let me know
