Process reviews with "Enable explicit process reviews - OFF" - no reviewed button

We have chosen to use the "Enable explicit process reviews - OFF" option so that our processes automatically change the review date to 24mths (our chosen period) from the last PUBLISHED date.

However, the "reviewed it" button is then no longer available and the only way to show a review was done is to edit the process and change something. Even if no change is required, we are forced to make a change (we just add a full-stop somewhere) and then we have to put it through approvals before we can re-publish - this is very inefficient.
