Thanks for the quick reply
I'm not sure that at this moment in time I have the needed energies, knowledge and skills to deal with a building a Generico template from scratch, but it's good to know it's possible. Thanks for the reference.
I made a template that pulls info from the profile of any user in a course with the instructor role. It pulls the name, email address, profile description and profile picture and displays it in a bootstrap card.
You can probably modify from here. You could just duplicate and change the roleid value and stack them and re-create the effect of the Course Contacts block.
