Limited Number of Delivery Addresses on Purchase Order

Limited Number of Delivery Addresses on Purchase Order

Hi, I am pleased that the new Zoho Books has a Purchase Orders function.  I am just starting to use it.  However, it looks like I can only have 3 delivery addresses.  We have one main supplier and ship directly to many different addresses.  Can the delivery address be linked to a customer - or just open the number of addresses? Any work around?

Thanks,
Allison
