Customize the mails adobe sends to new users to download acrobat enterprise

Hello,

I'm deploing adobe enterprise pro for some customers. Every time I add a new person in the reseller-console, adobe sends a mail for registration and after that a "welcome" message to download adobe acrobat.

Is there a way to customize these 2 mails?

The reason why i'm asking is that the end-users should not download acrobat by them selves, so i do not want to send them a download link.

Thanks in advice!
