Hmm, this is a good question. First thought was maybe a tagging system for target points, but no clue how this works as of yet. Remember seeing a note about object tagging added to an earlier version. If this is a solution, can we get a write up in the docs on that?
Failing that, suppose one could make a new target point class for each set and load those locations into a unique array…but that would be horribly convoluted and difficult to keep in order. So, would be curious myself what recommendations turn up for this. In fact, would be quite good if in the next release we could get much AI love.
