How to apply changes to NOT the latest commit?

Question

git

There is a branch and three commits in it AAA-BBB-CCC
All commits were sent to PR
Next, edits were made, but they need to be applied to the BBB commit
If I needed to merge them from CCC, I would use --amend, but what about in my situation?

Answer 1

There is a branch and three commits in it AAA-BBB-CCC ...
Next, edits were made, but they need to be applied to the BBB commit

git commit -a -m fixes
git rebase -i AAA

move fixes after BBB, replacepick before fixes with fix.
Everything is the same, but automatically:

git commit -a --fixup BBB
git rebase --autosquash AAA
