does anyone have experience with modifying the startup list of an EtherCAT CoE device from the PLC? Or modifying the startup list over ADS?

I can’t find any documentation describing this but it must be possible somehow. I mean the XAE is modifying it. Maybe I need to fire up the ADS monitor and see if I can log what happens under the hood when you modify a entry. I’m unsure on which target port to monitor in that case, any pointers there would be helpful also.
