The Reason manual shows another option for automating multiple parameters that brings up a dialog box with check boxes next to each parameter, where you can check all the parameters you want to create automation lanes for in one shot. I don't know, maybe that was taken out in version 6.5 because you're supposed to be able to find that option from the Edit menu or context menu and it doesn't appear to be there.
Just go to rack and right click the knob or slider you want to automate, it will create a seperate lane for it in the sequencer.
