Brandon, I'm afraid there is no easy way how to handle this in IPAM today. Maybe creating custom reports containing IP addresses stored in custom fields could help here, but it's still not the perfect solution. I will let PM know about your feature request, so he is aware of it when planning next releases.
If you would like to gain community backing of this feature request, I would recommend posting this in the IP Address Manager Feature Requests. The PM can also log your request there.
I need this as well.
you guys may create request an feature request for this if it is an important thing for you.
