Embedded Coder: how to modify model interface with a ConfigSetRef?

Hi all,

we have recently migrated from multiple ConfigSet for multiple (referenced) models to a single ConfigSet, linked as ConfigSetRef. Now, the dialog to configure the model functions is greyed out:

Questions:

• Can the model interface still be configured using ConfigSetRefs?
• If so, where can it be done?
• Can the model interface be configured by command line?

Kind regards, Matthias
