Don`t know if my new tool might be of help here? It has a grab function that allows you to move the relevant parameter in a plugin gui and it will assign that parameter in the Instr. Automation device: --also works for effects if needed. If it is already an assigned parameter then it will just select that parameter in the automation list for you, ready to automate.
3.1 beta needed, grab function is the [G] button:

I’ve tried using it on several occasions but I’m not having any luck. Omnisphere’s parameters just show up as numbers, and there’s I think literally thousands of useless parameters to scroll through in Reaktor.
Drag and Drop Sample Export would be pretty sweet
