An alternative to the missing `bio run --all`

I have a default_envs defined in my platformio.ini file. When I type in pio run, the most important code, specified by default_envs is built. Sometimes, when I have more time, I want to run all my envs, sort of like pio run is supposed to do when the default_envs is not defined.

Is there a way to do this? I don’t like changing my platformio.ini file just so I can do this, since, as you probably know, each time that file is changed, all my previously built binaries get cleared out and I have to rebuild them again.

I also don’t like the option of doing a
pio run -e env1 -e test -e myapp -e another-test -e colorwheel -e …
That’s not great since the number of projects changes.

Any ideas? I am surprised that there is no pio run --all. I’m hoping to be wrong.
