I like the face to face very much. But I found it a pain to add users to these sessions. Meaning I have a blended format of a course on Moodle and my users are already in cohort. I have a face to face session integrated in this course. I created groups because I have a few face to face sessions in the morning and in the afternoon. I put conditional access to the morning or the afternoon sessions depending on group affiliation (group A or group B).
It would be so practical if one can add a cohort or a group directly to a face to face.
So far this is done manually. which is a pain because i have to upload users, enrol them in their cohort, add them to their groups. But I have also to add them to the face to face manually.
