`reason:review-requested`, but exclude team reviews?

When filtering PRs, I found

reason:review-requested: “You or a team you’re on have been requested to review a pull request.”

which is super useful. However, sometimes you want to see PRs where you have been mentioned directly (as opposed to indirectly via a team). Basically, I want a filter like this:

reason:personal-review-requested: “You have been directly requested to review a pull request.”

I had a look at some github docs but couldn’t find an easy way to do this.

Does a feature like this exist? If not, can one be created?
