thank you, and what if the initial model calculates a measurement output for every group member (via trigger device setting) as a first stage, and we need at the second stage to sum up all the outputs for all members of this group into a measurement (or any other way) in order for example to show the working hours for a specific group. What is the best practice to achieve it? How to associate this specific new measurement (called for example group aggregate) to the whole group?
