How do you side chain a kick and 808 bass sample in a groove agent instance?

I have three kicks and a long tailed 808 bass all within a groove agent instance, and would like to know if here is a way of side chaining them within groove agent. If not what would be the best practise ?

Although I have no knowledge of sidechaining internally, I would suspect there will be a way, easiest way is to duplicate the instrument and split the midi information, it also would give you easier access to editing features, I would imagine sidechaining inside a plugin would be convoluted and clumsy to edit, that is, if it is possible.
