Issue : Ability to send emails via filter subscription in PDF or any other format as an attachment

Summary :

• Presently user can create an email subscription for a filter.

• The email received is in the form of HTML and a table
• There is no option within the subscription to select which format we would like to have the file sent to the email

Suggestion :
It would be great if there is an option within the filter subscription to have the users select if they want the file in HTML or PDF, or CSV.

Workaround-
For now they can only export manually from the filter the file
