How to add people to the default assignment list

Hi all,

a while ago I asked how to add support groups to the default assignment list. This worked like a charm, but now my collegues ask me to add their name to this list and I have not yet found how to do that. I presume that I will have to go to the SD.IncidentEscalation workflow and on Model:Primary I will open the Declarations component. But from here I do not know what components to add and what the configuration is.

Is there anyone that can help me with this? We run SD 7.1.

Thank you

Kind regards

Koen
