Great, did you find how to link both the dropdown and plain text CC to the same xml node so that the value displays in the plain text CC and reflects the value of the dropdown CC entry? This avoids the need for vba to connect the two. You will still need vba for the dependent list of Snr Ops but it does simplify things.
Getting the CC by its Title or Tag is
Code:
ActiveDocument.SelectContentControlsByTitle("TLName")(1).Range.Text = strDetails
'You can also do it by Tag
ActiveDocument.SelectContentControlsByTag("TLName")(1).Range.Text = strDetails
