Automatically detect subfolders with git repository

[NN---]

Describe the feature that you'd like
VSCode builtin source control tab can discover automatically subfolders.
It would be nice to support this in Git Graph too.
Right now Git Graph I need to add them manually.

Given:

project/
   .git/
   subproject1/
      .git/
   subproject2/
      .git/

VSCode shows:

project
<Message>
[Commit]

subproject1
<Message>
[Commit]

subproject2
<Message>
**[Commit]**
