Add a column for the date of last client activity

Organizers/Delivery Report   and  Tax Returns/Delivered Returns:

It would be beneficial to have a column for the date of last client activity.

Benefit(s):

• Allows us to confirm it is not in their spam folder, there by eliminating the need to reach out to the client for pages or organizers...   (even though we say we are not going to follow up once sent - we always do;)
• Efficiency:  I can  only view this info now by looking  in user tracking for each return.
