I currently manage 8 listings, 2 are my own and 6 I co-host for other people.
The 'Payout routing rule' in the payment settings is a great tool to segregate earning from each listing into different accounts, HOWEVER currently allows this for only the listing you own, I think it will be really great if Co-hosted listing was also available in this option either 'as one entry' or even better if 'they were shown separately'.
Hope this makes sense.
