Importing Users: User welcome email template is not available for editing?

Currently, when adding users one at a time, I can customize the welcome message on the fly. This option is NOT available to me however if I am adding users via the CSV Import mechanism. Interestingly enough, I am asked if I want to send a welcome email to the users, but I don't know exactly what the message says nor am I able to edit it.

ASK:
As an Aha Admin, I would like the ability to see/edit the default template. Preferably this email template would be shown on the Account Admin Screen (Account -> Profile -> User Onboarding)
