How to put VST Compressor with Sidechain Function on Return?

[Ludbek]

Hi Guys,

I want to create a Send on My Auxiliary Channel with the "Sidechain Function" with Compressors CROSSCOMP or BUSCOMP (or another Waves Compressor for example). It's Possible? In this moment I use Ableton The Glue and traditional compressor for that function.

Thanks
