Please add the "Send a copy" block to the E-mail activities in CiviCase. Currently, when adding an activity, such as a phone call or meeting, I can choose to "Send a copy" to multiple Case Roles. However, that block does not appear when adding an E-mail activity to a Case. There are a number of instances where an e-mail needs to be sent to a number of Roles on a Case. With the current setup, at least from what I can find, there is a much higher chance I will unwittingly omit a Role or worse, send it to someone not associated with the case in question.
