Custom email template for beta test invitations
It would be useful to be able to modify the beta test invite email template. Right now, the only mention of the developer name is in the subject of the email, which could be somewhat confusing for users. In addition, other information in the email, such as the FAQ, isn't always necessary, and having both the US and JP invite links close to each other can also cause issues.
I would like to be able to modify the invite email to fix these issues and add additional testing instructions. If it's not possible to allow developers to modify the invitation email, it would be nice to be able to "silently invite" users, such that they don't get an invite email from Amazon. This way, the developer can just send out the invite link in an email to each beta user, without the user receiving two emails.
