Revisionary and PressPermit – if post is EDITED send for approval

We have the following setup:
We have a custom post-type, and using PressPermit each single post is assigned to an editor, and that editor can ONLY edit and view the post assigned to them.

What happens:
At the moment, an editor can publish immediately any edits, or if they CHOOSE they can Send for moderation.

What we need:
When an Editor edits their post, we need it to NOT go directly online but to be sent for moderation ALWAYS.

We’ve read elsewhere that this is achievable with Revisionary, but we can’t figure out how to do it. Is it actually possible?
