Push all git repos sequentially, in vscode multiroot workspace

Question

I use a multiroot workspace in vscode. In the source control sidebar, I can commit changes and push to origin (for each repo).

But often I have to push multiple repos. Although I can click the "Sync Changes" button for each repo:

• I can't push too many at once (our git server doesn't work well under load)
• and each push takes some time (~20s)

So doing this for a few dozen projects is a chore.

Is there a "push all repos" feature, which pushes sequentially?
