Updating status checks on merge of PR instead of head

[harryfinbow]

Describe your use-case which is not covered by existing documentation.

If I use the branch specifier origin/pull/4/merge instead of origin/pull/4/head the status checks are trying to write to the wrong commit (the result of the merge and not the PR head). Are there any documented ways to do this?

Reference any relevant documentation, other materials or issues/pull requests that can be used for inspiration.
