How can we manually review gift card orders before approval?

[CBR1]

We've had a number of issues with fraudulent gift card purchases and have since had to remove them from our site, but we'd like to get them back up! Is there a way a customer can place a gift card order and we manually review it before accepting it? We're thinking any time a customer purchases a gift card over $X and/or attempts multiple purchases within X hours. 

Thanks in advance!
