Email alerts features

Hello! Is there possibility to:

  1. add email subject & body to email alerts
  2. send in emails final excel file generated from SQL query (not just link to SQL query page itself)
  3. show first N rows of table including column names in the email?
  1. no
  2. yes, enable attachments in the subscription
  3. yes, that's shown in the subscription (only a few rows are shown)

thanks a lot
