Hi @cedgar,
Unfortunately no, at least not through a feature in the teacher dashboard. Here is an explanation why this is more difficult for a few reasons including Code.org’s international base. I understand the frustration. There are some good workarounds. Here is a solution that asks you to have the students change their name. Depending on the age of your students and your current teaching environment (hybrid, remote, etc.), this may be challenging. So, another option is to go to the main classroom dashboard, go to the gear for the class to “manage students”. Then, go to the gear next to “action” and choose “edit all”. From here, you can edit all students at once.
I hope this helps,
Michelle
