Hopefully we’re missing what is an existing feature, but when writing a blank letter, is there an automated way we can add “cc” contacts to the letter from the list of contacts already tied to the matter? 

See below as it doesn’t appear this option exists.  It would be great to have this option, maybe in the form a new tab listing the contacts?

At this point, we type-in relevant parties manually.  We’ll somehow survive, but it would be nice to have SB do the work...
