Hi,
If I understand your question correctly, I would say yes. You need to set all intensity in the same playback though, same goes for colour. For fixtures without an intensity channel you can set the 'Virtual Dimmer' in the patch.
Just create a playback with colours, and a playback with intensity at different values. Make sure the faders are at 100% in Cuety.
They get mixed HTP, so it should work for all fixtures.
