Unlock chapter request when there is already a schedule but not both, or an update schedule

Some series already have release schedule for them, with queue for releases, but not for unlocks for example, so it becomes impossible to use the chapter requests to request new unlocks in this situations too, as in the image for example.
In the other situation we can already request for new chapter when there is an unlock schedule, so it should still be possible to to it the other way I think.
