Ability to Manually Edit IP Time Zone
It would be great to have the ability to manually edit a contact's time zone. The IP address time zone is not always accurate in terms of when a contact needs to receive one of our emails. For an upcoming email send, for example, I am having to upload 4 different lists (each with contacts in a specific time zone) and then clone an email 4 times so that I can schedule each email to send according to the specific time zone. This is obviously a tedious process and would be much more beneficial to be able to have a field in one list where you can manually include the time zone and have the email send based upon the time zone included in that list.
