Copying Channel Settings ignores Sidechain

While converting some of my old Folder+Group tracks to the new Group Folders, I noticed the following:

  • My group channel has a Frequency plug-in, Sidechained with another track
  • When Ctrl-C the Channel Settings of Group Track, and then Ctrl-V’ing it to the new Group Folder, Frequency is copied, however, it loses the Sidechain Source - why is that?
