BUMP: I submitted this idea in 2019. Says "to be reviewed". Still desperately need this functionality for multiple sites.
By adding this field, you would allow the customer to ship to multiple names at the same address easily. The idea is that they wouldn't have to add a new record to their address book for every different name.
The larger issue here is the address book/location functionality. Would love to see a revamp of that part of the check out process but the addition of this field would be a decent band-aid.
