In my experience this is something that journals ask for constantly. I think that I have instructed the use of section editor role for this purpose at least for 5 journals in our installation alone. It seems to be fairly common that a person closely working with a journal also sends in manuscripts.
Of course using the section editor role is not ideal and that is why I suggested this a while ago: New role (permission level) to to solve a central problem in OJS But there can be other solutions as well of course.
