The process to review and unmatch properties is very time consuming. Every time you click Unmatch, it does not go to the next record, instead it kicks you out and you have to select the next matched group and start the process again. To quickly go through records, you do not select Unmatch and instead select "advance to the next group". The issue is this leaves you with a list not matched groups that you want to get rid of but cannot. If there was the ability to do a mass Unmatch action the process would be much faster. The other option would be for the system to advance to the next record after clicking Unmatch.
