Since I believe it is possible to realize with Rules, I tried to to this, but I found, that I can't do this at the time :( But as a help, I can suggest you to take a look at these two topics:
https://ipsguru.net/forums/topic/116-rule-on-report-status-change
https://ipsguru.net/forums/topic/924-rule-triggering-on-report-status-change
Reading those topics, you can try to create your report rules by yourself, or maybe change something to fit your needs.
