RobotExpert is a different product than Process Simulate that was developed in order to support industries, use cases, workflows and needs that are different than Process Simulate. This is why there is no 1:1 match between RobotExpert and Process Simulate. BTW, there are many more functions that exist in Process Simulate and are missing from RobotExpert and there are commands in RobotExpert that do not exist in Process Simulate.
There is no plan to add the functions you mention to RobotExpert.
What workflows are you interested in and for which industries? As an example, classic auto biw use cases cannot be completed in RobotExpert, but general arc welding processes are good fit to RobotExpert.
