***Note from Migration:***
Original Title was: Allow users to pick measures from one dataset in LineOnLineOverlayer when multiple measures exist
Currently when multiple sets of data enter the LineOnLineOverlayer transformer, the first set, if has measures, will be used for the segments in the output. If the first set does not have measures, the segments in output will not have measures. The order of the data going in is by the reader and then alphabetically if all the datasets are from the same reader. So if you want measures from a specific dataset, you will have to add an additional reader to host that dataset and make sure it is read in first.
My idea proposal is for a new parameter on the transformer to allow the users to pick the measures from one of the datasets.
