Lifecycle Revision Help

Our company just decided on implementing pdm into our solidworks and I'm having 1 problem with setting up the Lifecycle revision.

I have three main lifecycle statuses: Changed, Review, Approved.

Currently for their to be no errors with my test scenarios I have Changed and Review as both Working Copy and Primary checked. Approved is only Primary.

I would like to (if possible) have Changed and Review to only have Working Copy selected as I don't want the option to increase the revision at this stage (trying to avoid human error) . And I want the revision to increase only at the Approved status.

If anyone can help guide me through this, that would be much appreciated as I am new to pdm.

Thanks!
