Provide a way to enter package delivery/received date

Provide a way to enter package delivery/received date

Good day,

Currently, the Packages module provides the means to enter a shipment date, as well as mark the package as delivered. However, there is no way to enter the date the package was delivered to/received by the customer--at least not for manual shipments. 

It's important for us to keep a record of when our customers receive their packages, and it seems like a very fundamental piece of business data. Can you please make it possible to enter the delivered date?

Thanks very much, and keep up the great work!

Chris
