Answer 1

For the merge commit message, I found that I cannot amend it by using rebase, at least on gitlab. It shows the merge as a commit but I cannot rebase onto that #sha. I found this post is helpful.

git checkout

git rebase HEAD previous_branch

This three lines of code did the job for changing the merge commit message (like author).
