Another item that isn't a problem, but neither is it a feature request.
I just grouped two different fixtures together, that both have different light loss factors.
It would appear that in the luminaire schedule the displayed light loss factor is an average of the two.
Since they actually don't have the same output and contribution to the result, this displayed figure isn't really based upon any meaningful factor. Is it better to put a note such as 'N/A', or more preferably 'Combined' or some such thing?
