Hi all, I have the following problems while calculating the Robot Working Hours:

  1. Suppose I have three Robots (Robot_1_A and Robot_1_B, Robot_2). How can I group those robots in a way that only Robot_1 and Robot_2 are displayed in a bar chart where the Robot Working Hours are calculated with the formula sum([Runtime In Seconds])/3600?

  2. How can I give those robots then custom labels? Example: Robot_1 becomes “Business Process 1”
