Option to specify reviewer per KB article

Option to specify reviewer per KB article

Hi, 

I have realised that reviewers are being emails for any article being reviewed as a group and it's not possible to send articles to individual reviewers as you can imagine not all KB articles are to be reviewed by the same group of reviewers/reviewer.

In addition I have found out - possibly a bug - that all reviewers from all categories ( despite reviewers specified per category) are being notified about articled to be reviewed.

Can you please advise what can be done about this?
