We have group training events. Sometimes people come along when not expected (or change their date) They have the link from a colleague. This is fine, but we want to add them to the event to show they attended and then they will receive all the automated workflow emails afterwards. How can we add them in?

Today’s example is that 3 people attended todays event when actually they booked last week and were marked as no show. They used a colleagues link and joined with them today. Colleagues are booked on and receive the evaluation form, link to digital resources and follow up check in workflows, but the 3 people won’t get anything. 

Do i have to manually email them or is there a way to add them in even after the event? I can’t seem to find an option for this but really need it.

Thanks
