I’m a bit late at this party, but I very much support this idea! Although there is a relevant (and still open) issue in the Git tracker, I only see the option of an “issue filter” mentioned indirectly in this comment: Add filtering options to new submissions list · Issue #2612 · pkp/pkp-lib · GitHub.
Yet, I think this could be a real improvement! Otherwise, since the editorial organization in OJS seems to pivot around sections, this practically forces editors to cram the concept of “(special) issues” into the concept of “sections”, as often recommended in this forum (e.g. Assign article to issues - #2 by ajnyga).
Did you meanwhile find a satisfying workflow for your journal, @Alina_T?
