The administrator of the account should be able to add a handful of email addresses to get the Weekly Digest Email.
Currently, the only way for anyone to get a copy of that email is that they have to be a named user, give them permissions to reporting and then opt themselves into getting the report.
So if the owner of the company, or the controller or a director of finance wants a copy, I have to either forward it to them with or with filter rules (but I don't care to receive it myself if I'm the admin), or I have to add one of the email recipients as a named user for $15-5 dollars that don't want or need any functionality of Shipstation except for this report.
TL;DR
1. Allow the administrator of the account to add one or more emails to get the Weekly Digest without taking up a named user slot.
2. Weekly digest should contain an Excel attachment so that the data can be consumed easily by biz folks.
