Can I set push-options (git push -o "...") in git config?

Git 2.10 introduced git push options (git push -o "my string").

Many command line options are configurable, and I was wondering if it was possible for this too. I was not able to find it in git-config, but perhaps I'm overlooking it.

So, would it be possible to add a (set of) default push option(s), to have ...

git push -o "r=joh.doe"

... the default when running ...

git push

?

^{Context: I am using this with Gerrit to directly assign changes to reviewers (documentation for reference - using compatible syntax <push-ref>%my_string). When uploading many changes and working in pairs to review each other's code it would be useful if I can add that person as reviewer at push-time already.}
