Open review, but not so open

Describe the issue or problem

I am using OJS 3.1.2.4 (need to upgrade, not much time, sorry)

I use open review.

But I would like authors not know how late are the reviews, or which reviews are already submitted, unless the editors consider the review process finished.

Is there a way to accomplish this?

What application are you using?
OJS 3.1.2.4
