As I've stated, based on the MSRP and street cost of myDMX, this feature is something I honestly wouldn't expect in MyDMX. It would be nice, but for me, this is more of a "Feature add" and hence it would fall outside of what they are willing to put into it.
As far as Compu Live is concerned, based on a previous posting you made, you said that this sort of functionality is also not in Compu Live. I would like to suggest that this sort of functionality be inplemented into Compu Live. After all, with Compu Live, you're getting a more full featured lighting package, so based on costs, it makes more logical sense to put this into Compu Live.
