Shared Parameters (I think) would be the way to do that if you wanted to add something there. I'm not positive about this though.
The Parameters in the Energy Analysis parameter group are inputs to our Heating and Cooling loads calculations, additional added parameters would not be factored into the analysis in any way. You also cannot add any additional choices to the various lists at this time. Is that what you're trying to accomplish?
