Wish: A `rerun-failed-tasks-only` tag I could use to ask CI to re-run only tasks failed in a prior commit

Often I upload a PR, and observe that X of XX CI tasks fail.

I then work on fixing (either by updating tests, or the code, or both). While not sound, I'd like the ability to instruct CI to prioritize (or only) run _previously failed tasks_, so I can get quicker results instead of waiting for 100s of tasks to re-run, many of which might be unrelated to the code I'm changing, and cause false-negatives (due to flakes).

This behavior would not be safe to land changes, but would make iteration time faster (at least for me).
