Stereo Sidechain/Key Input in Sonar?

Good afternoon folks!

I was wondering if it is possible to create a stereo sidechain in Platinum to pass audio data to Zynaptiq's Morph 2. Zynaptiq only installs the VST2 for Sonar which doesn't have the same sidechaining options available in the VST3 for Cubase for example.

The manual for Morph 2 has options such as quad mono and overlapped stereo in a quad bus but I cannot get anything other than two channels of mono morphing together.

I searched the forum and I could not find any previous reference. Could one of the gurus out there enlighten me?

If this post needs to be moved to software, that's cool too.

Thanks,
