Merge duplicate contacts after uploading vcards

Without realizing it, I had my Google account set as the default for my contacts. However, I would like all my contacts to be with my Apple account. So, I downloaded the vcards from my Google account and uploaded them into my iCloud account. This created a lot of duplicate accounts in my Apple iCloud account. Is there a way for my iCloud account to look for duplicates and let me decide if they should be merged?

Prior to downloading the vcards, Google listed a few contacts that looked like duplicates. It then gave me the option to merge them. It showed the information for both contacts and gave me the option to merge or not merge them. This would be very helpful for my iCloud account.

I know there is the option to delete one of the duplicates. This will take a lot of time because of the steps involved.

• Review the contacts and decide which one needs to be deleted.
• Click on 'Edit' at the top of the page.
• Click on 'Delete Contact' at the bottom of the page.
• Finally, click on 'Delete' in the popup in the middle of the page.

If something needs to be copied from one and pasted to the other, this is even more steps to follow.
