By "the string" do you mean the Alias? No, it is not possible. Using state detectors, it doesn't make sense to me to have to do that. Point event detectors are on a per-point basis already, so the data point that it applies to is known. Similarly, for a State detector (but not a regex state detector) the state is unchanging. So, I don't know why you would want to do that. It does make some sense for a Regex state detector, though, but isn't possible at the moment.
Mango has existed for quite a while, so there have been a few contributors. Of absolute noteworthiness are Matthew Lohbiler, who wrote Mango M2M, and Terry Packer, who is our senior developer. But, if you peruse our opensource Github repositories you may find others, such as myself, who have made contributions. A great many of the modules are written by contributors. Most classes do have an author documented at the top, but this is not always updated to reflect everyone who touched a class.
