Format all Python files in a folder with black included inside the extension

[vtgn]

Hi!
I'm surprised I found no question here about this (I just found one on another forum with no answer), but I've configured correctly your vscode extension to format a python file on save, and I want to format all the Python files of my project by using the same black command as the extension. And I found no way to do this, excepting by installing myself black and launch the command manually. =/
Is it possible?
If yes: How?
If not: Why?

Thanks.
Regards.

So it is not possible for now, shame... :/
