Give members multiple email fields

Hi! I’m a few days from launch but have already started signing folks up. I don’t know if this has come up in the past but I did have this thought: It sometimes happens that two spouses give once but both want to be on the list. I’m then manually making the account for the second person. That said, it’s really a single give. Ideally it would be great to have multiple email accounts associated with a membership. Perhaps a more simple use case would be someone who wanted to get the emails at two accounts… work and home. Has this ever been considered?
